What medicine is used to make a pepper tree crazy? The whole pepper died, what medicine should be us

It should be that the pepper tree is crazy, too much urea is applied, urea contains a lot of nitrogen fertilizer, too much nitrogen causes the pepper tree to grow wildly, you can use the powder potassium dihydrogen phosphate to control the prosperity, and then spray some amino acid foliar fertilizer to add more nutrients to the pepper.

The amount of nutrients such as nitrogen, phosphorus, and potassium absorbed by peppers is also different at different growth stages.

1) From the emergence of seedlings to the emergence of buds, the plant has fewer roots, small leaves, and requires fewer nutrients.

2) From budding to early flowering, the growth of plants accelerated, the plants expanded rapidly, and the absorption of nutrients increased.

3) From the first flowering to the full flowering and fruiting, it is the period of vigorous vegetative growth and reproductive growth, and it is the period when nitrogen is absorbed the most.

4) From full flowering to maturity, the vegetative growth of plants is weak, and the demand for phosphorus and potassium is large.

Summary: Pepper flowering to fruit setting needs more nitrogen fertilizer; Fruit set to maturity, potassium fertilizer is required.

Pepper topdressing is generally in the evening, about 15 cm away from the roots, and then irrigated and watered immediately after chasing. The principle of top dressing is a small amount many times. After the first flowering period of peppers, the first top dressing is carried out when sitting on the fruit, and the peppers are used as fresh peppers to eat, and dry peppers are made.

When making top dressing of fresh peppers, nitrogen fertilizer is biased, but not excessive, otherwise the fruit setting rate of vigorous growth is low. The focus of making dried pepper is to chase nitrogen fertilizer on the basis of nitrogen fertilizer and partial potassium fertilizer after the fruit set is red. Potassium is the element that determines the color and quality of dried peppers.

During the growth period of pepper, it is best to combine pest spraying control, after fruit set, appropriate spraying of ribery Yanwo amino acid foliar fertilizer and Yanwo powder potassium dihydrogen phosphate solution, combined with imported chelated boron fertilizer from Shangyanwo, can effectively prevent flower and fruit fall. At the peak of fresh pepper harvesting, peppers need to absorb a large amount of magnesium fertilizer, magnesium nitrate solution, and spray several times. When pepper is deficient in boron, you can use Yanwo boron fertilizer, which has a high safety factor and is not easy to cause poisoning.

What does it mean that the branches of the pepper tree are crazy? Isn't it.

Because you have too much nitrogen fertilizer, you have too many branches and leaves.

If you look like this, it's not good. It should be rushed.

It is better to fertilize phosphorus and potassium fertilizers a little more.

The control agent can be fluorinylurea, manganese-zinc, oxazolidinone and its compound preparations, such as DuPont-Jikuaijing, Yibao, enoylmorpholine + pyraclostrobin, etc. Generally once every 7-10 days, peppers should be treated as soon as possible after bacterial wilt. At the beginning of the disease, 77% kocide wettable powder 800 times can be sprayed continuously 3 times, with an interval of 5-7 days.

When bacterial wilt occurs in peppers, it is usually accompanied by insect infestation and is treated with insecticides, and soils with high humidity are susceptible to this disease.

In the early stage of bacterial wilt, the main damage is to the branches and leaves. At first, the branches and leaves of the diseased part wilted, and gradually spread to the whole plant, the color of the whole plant became light, the leaves were burnt yellow, and the distinctive feature was that the appearance of the stem of the diseased plant was not obvious, and the vascular bundles turned brown when the diseased plants were dissected, and when the slices were sliced, the milky white mucus overflowed from the vascular bundles, which was different from blight. As for the problem that peppers are prone to die in summer, this is mainly due to the high temperature and rain in summer, and the drought is caused.

Moreover, as a shallow root system, pepper is prone to stem rot, wilt, root rot, etc.

Peppers are harmed by high or low temperatures, when peppers are harmed by high temperatures, they should be watered to cool down at night, and shade nets should be built in places where conditions permit, shade the sun, and reduce the ground temperature of peppers. When the temperature is low, tie up the greenhouse and raise the temperature. Root burning caused by improper fertilization For root burning caused by the increase in fertilizer concentration in the soil after the application of chemical fertilizer without watering in the case of low soil moisture content, it is necessary to water to reduce the fertilizer concentration in the soil, restore the growth of plants as soon as possible, and reduce losses.

To sum up, when planting peppers, it is necessary to plough the soil in advance, turn over the soil, and expose it to the sun, which can kill most of the germs in the soil. Peppers should not be cropped continuously, and the soil before crop rotation should not be Solanaceae. At the same time, the seeds should be disinfected before seedlings, and the seeds can be soaked in 1% copper sulfate solution for 20 minutes, which can destroy the germs on the seeds.

Cayenne peppers should be treated as early as possible, sprayed on cloudy or sunny days. When it rains, it should be sprayed again within 6 hours.

Peppers are particularly easy to die, mainly related to soil deterioration, and will reduce a large part of the soil after conditioning the soil, but in addition to changing the soil, we still have to use medicine, because after all, there are germs in the soil. At present, there are two major soil-borne diseases of pepper dead trees, one is canker disease, the other is medullary necrosis, and both of them are bacterial, once these two diseases occur, they can multiply and spread in the vascular bundle and will damage the phloem and xylem and then cause water and nutrients to be transported normally, and a little pepper will wilt and die. <>

Therefore, for the dead pepper trees, on the basis of soil improvement, we should also use pesticides to irrigate the roots for prevention and control. If diseased plants are found in the shed, they should be treated with pesticides as soon as possible. Since the two diseases mostly occur at the base of the stem, the sprayer nozzle can be removed and sprayed down 10 cm above the diseased part when the liquid reaches the surface.

Eggplant sclerotinia sclerotinia can be sprayed with 430 times of "gray kernel net". Eggplant stem base rot can be used to irrigate the roots with "special for wilted root rot". <>

Generally, spray once every 5-7 days. 2-3 times in a row. Generally, irrigation 1 time in the seedling stage, 1 time before a spike of fruit flowering and fruiting, irrigation 1 time every 20-30 days in the subsequent growing season can basically be well prevented, if it has happened, it should immediately stop flood irrigation, pull out serious diseased plants after irrigating roots to control the disease and then water and fertilize normally.

The implementation of crop rotation, deep ploughing and soil modification, combined with deep ploughing, increased application of organic fertilizer, phosphorus and potassium fertilizer and micro fertilizer, appropriate application of nitrogen fertilizer, improve soil structure, improve fertilizer and water retention performance, promote the development of root system, and plant health. Fully cover the mulch, strengthen aeration, adjust the temperature and air relative humidity of the greenhouse, so that the temperature is maintained at 25 30 during the day and 14 18 at night, and the relative humidity of the air is controlled below 70%, so as to facilitate the normal growth and development of eggplant, which is not conducive to the infection and development of diseases, and achieves the purpose of disease prevention and control. Pay attention to observation, find a small number of diseased leaves and fruits, immediately remove and bury deeply, find that the stem is diseased, and immediately use 200 times 70% mancozeb solution to smear the lesions and eradicate the pathogen.

It is recommended to pay attention to whether there are any borers in the roots, or if there is corruption or lesions in the roots. If there are moths, you can choose insecticides to carry out **, if there is rot in the roots, pay attention to whether there is too much rainwater accumulation in the roots.

Some insecticides can be used**. In this way, it can effectively prevent the death of peppers, and can also better help peppers to grow, which can prevent pest problems.

It is necessary to use the drug control of the blight, or the drug to improve the pepper seedlings, pay attention to the correct amount of the drug, and understand the requirements of use.

You can choose to use pesticides to solve and prevent the pest problem of peppers, and then wait until the situation of peppers has eased before fertilizing.

Cotton aphid Zanthoxylum bungeanum often gathers on the young leaves and young shoots of Zanthoxylum bungeanum to suck sap, causing leaf curling and flower and fruit dropping, and the viscous honeydew excreted is easy to induce bituminous coal disease and affect the photosynthetic efficiency of leaves. The control method is as follows: spray 40% dimethoate 1500 times alternately, 40% amithion, 1000 times of 40% hydrothion, 4000 times of 50% aphid net emulsion, and spray 2-3 times continuously to control the hazard every 10 days.

In spring, the underground pepper tree is sprayed with phosphine granules or chlorpyrifos to control underground pests, imidacloprid is used for aphid control, spiroethyl ester thiazinone is used for scale insects, jumping nails, and inulin pesticides are used for wind butterflies. Before germination, the whole tree is sprayed with Baumé 5 degree stone sulfur mixture, and the base angle of the main stem and branches is sprayed to all the corners. Eradicate germs, leaf mites, and insect eggs.

If there is no disease, try not to spray.

In spring, pests such as Zanthoxylum bungeanum scale insects, narrow gilding insects, and Zanthoxylum bungeanum leafminer jumping beetles began to move from the wintering sites one after another, and the damage intensified with the growth and development of Zanthoxylum bungeanum trees. Therefore, it is necessary to strengthen the prevention and control of spring pepper insect pests. Before budding, the whole tree is sprayed with 3-5 degrees of Baumé sulfur mixture.

Before germination, spraying with higher concentrations can reduce the base of a variety of pests and diseases, reduce the annual medication, reduce costs, and have significant effects. At the same time, it is necessary to prune the branches with serious diseases and insect infestations, and bury them deeply or burn them. Prevent the further spread and spread of pests and diseases.

1. Spring: Aphids are easy to break out during this period, so you can spray 1500 times dimethoate emulsion or 1:1000-2000 times zinc sulfur emulsifiable concentrate in April.

2. Summer: Leaf rust is prone to occur during this period, and stone sulfur mixture can be sprayed from June to August, and the number of times is 1-2 times. 3. Autumn:

During this period, it is easy to break out of the longhorn beetle, and the insect tips can be cut off when harvesting peppercorns, and the larvae can be killed with wire hooks and plugged holes. 4. Winter: spray stone sulfur mixture to prevent leaf rust.

First, what pesticides are being used in the pepper tree now?

1. Spring. (1) At this time, the leaves of the pepper tree are susceptible to aphids, which will suck the sap in the leaves, causing the leaves to roll backwards.

2) In the middle of April every year, spray Xerin emulsion (1500 times liquid), or spray dichlorvos solution (1:1000-3000 times), zinc sulfon emulsifiable concentrate (1:1000-2000 times), or you can use laundry detergent, urea solution, and water according to 1:

The ratio of 4:400-500 is prepared, and then sprayed, and the control effect can generally reach about 95.

2. Summer. (1) At this time, leaf rust is prone to occur, the damage site is mainly leaves, the leaf surface of Zanthoxylum pepper will appear in the shape of round, the color is light yellow lesions, and then the color of the lesions will gradually deepen (yellowish-brown), and will produce powdery, orange-red spores.

2) Spray the stone sulfur mixture (1-2 times) from June to August, or spray 1000 times of methyl tobuzin solution for control.

3. Autumn:(1) After the beginning of autumn, Zanthoxylum bungeanum is susceptible to the harm of longhorn beetle, and its larvae will eat the branches, which will lead to the death of the whole plant when the situation is serious.

2) The control method is to completely cut off the insect tips and burn them when harvesting pepper in autumn, or use wire hooks to kill larvae, and then use cotton dipped in kerosene (or Bataan powder mixture) to plug the cavities.

4. Winter. (1) At this time, it can be combined with pruning work to remove fallen leaves and weeds under the canopy, and burn them, and then spray 2-3 degrees of stone sulfur mixture to prevent leaf rust.

2) When pruning in winter, it is also necessary to pay attention to killing pupae to prevent the harm of longhorn beetle. After summer, aluminum worm can be sprayed on the plant to poison the larvae, and the adults can be manually killed.

2. Can you eat pepper three or four days after being sprayed with pesticides?

1. After 3-4 days of spraying pesticides on peppercorns, it is generally not edible, because even the residual period of general pesticides is usually about 7-15 days, and if organophosphorus pesticides are sprayed, the residual period will be longer, so it is recommended to determine the harvest and eating time according to the type of pesticide sprayed and the drug instructions.

2. Different drugs have different residual periods, and the harvest time must be ensured to be outside the residual period of the drug after the pesticide is applied to Zanthoxylum, because at this time the drug has basically been decomposed to the extent that it is harmless to humans and animals. If the drug breaks down slowly and has a long residual effect (such as oils), it is difficult to wash off with water, and it is risky to consume.

1. Replenish water: Irrigate the roots of the pepper tree, soak all the soil, and water 3-4 times a week in the later stage. 2. Block strong light

Build an awning for the pepper trees to keep them out of the light spark. 3. Disease prevention and control: remove the diseased leaves and diseased plants of pepper trees and destroy them in a centralized manner.

4. Precautions: Usually apply more rotting organic fertilizer and phosphorus and potassium fertilizer to pepper trees.

1. Replenish water

Pepper wilting can be caused by insufficient water in the soil, and the plant can only thrive if sufficient water conditions are maintained during the growth period, at which point it is necessary to immediately water the roots of the pepper tree, soak the entire soil, and water 3-4 times a week in the later period.

2. Block strong light

In summer, when the temperature is high, if you take shade measures for the pepper trees in time, it will cause the plants to develop sunburn and wither, so build an awning for the pepper trees immediately when the light is strong, and keep the astigmatism illuminated.

3. Prevention and control of diseases

After the pepper is attacked by blight, leaf blight, leaf mold and other diseases, there will also be wilting, and the diseased leaves and diseased plants need to be removed immediately and destroyed in a centralized manner, and then the plants are sprayed with 800 times of methyl tobuzin solution.

4. Precautions

In order to improve the disease resistance of pepper trees, more rotting organic fertilizer and phosphorus and potassium fertilizer should be applied during the usual management period, the amount of nitrogen fertilizer should be controlled, and the watering should be diluted after fertilization, and water accumulation in the field should be avoided to avoid suffocation of the root system due to lack of oxygen.

Summary. Hello, this is pepper soft rot .

Hello, this is pepper soft rot .

Pesticide control: spray 4000 times of 72% agricultural streptomycin soluble powder, or 4000 times of neophytomycin, or 500 times of copper succinate wettable powder, or 500 times of 77% copper hydroxide wettable powder, or 300 times of 14% copper ammonia aqueous solution.

Other measures Implement crop rotation with non-Solanaceae and cruciferous vegetables for more than 2 years. Clean the field in a timely manner, especially remove the diseased fruits, take them out of the field, burn them or bury them deeply. Cultivate strong seedlings, plant them in a timely manner, and plant them reasonably densely.

Drain water in time during the rainy season, especially in the sewerage. Cultivated in protected areas should be strengthened to prevent excessive humidity in the shed.

It's better to buy those medicines.

Hello, neophytomycin is very easy to use.
