What pesticides are used for vegetable leaf rot when it rains, and what pesticides are used for vege

Hello friends, it is not possible to prevent rotten leaves with pesticides when it rains, because there are two reasons for rotten leaves:

First, continuous rainfall causes excessive soil moisture and lack of oxygen in the root system, which cannot grow normally, resulting in insufficient nutrient supply to leaves, resulting in leaf rot.

Second, the germs multiply, and on rainy days, the bacteria in the soil are invaded by the bacteria due to the rainwater hitting the leaves, causing leaf rot.

Solution. Drainage and nutrients, farmland should do a good job of drainage in rainy days, which is conducive to the circulation of water, and then Dehua Xinlu foliar fertilizer can be sprayed so that nutrients can be quickly replenished through foliar absorption and reduce leaf rot.

Fungicide, if there is a large area of rotten leaves, it may be a bacterial invasion, at this time you can spray fungicide to prevent and control, or mix with foliar fertilizer to fight, and it is better to hit once a week every few days.

Vegetable leaf rot is not prevented by pesticides when it rains, because the vegetable leaves are rotten on rainy days, because the bacteria in the soil are soaked into the leaves by rain, causing bacterial invasion, causing rotten leaves.

Drainage and nutrients, farmland should do a good job of drainage in rainy days, which is conducive to the circulation of water, and then Dehua Xinlu foliar fertilizer can be sprayed so that nutrients can be quickly replenished through foliar absorption and reduce leaf rot.

Sterilization of carbendazim and dimethazim is combined with foliar fertilizer spraying and furrow application of organic fertilizer.

The use of pesticides is not the most ideal solution to the problem of vegetable rot after rain, because pesticides can cause harm to the environment and human health. Moreover, pesticides are only a temporary fast, and do not solve the underlying problem. Here are a few suggestions for what you can do:

1.Timely picking: Picking vegetables as soon as possible after the rain can prevent them from continuing to rot.

2.Reasonable treatment: Dispose of rotten vegetables in a timely manner, and classify and put garbage into the garbage. It can be used as a first-row fertilizer, composted and reused.

3.Planting disease-resistant varieties: Choosing disease-resistant varieties can reduce the risk of vegetable rot.

4.Prevention first: do a good job in the early stage of vegetable planting, such as soil improvement, drainage, fertilization, etc. Maintain field hygiene and regularly remove trapped rainwater and weeds to prevent the growth of pests and diseases.

All in all, in order to avoid the harm of pesticides to the environment and human health, we should still try to avoid the use of pesticides and take prevention and control measures.

Vegetables can rot after rain, and you can use spring leimycin or mesomycin or bacteria-killing pesticides such as thiazolezinc or thiamethicone.

Summary. After the rain and flood disaster, the high temperature and humidity of the field environment are prone to a variety of diseases of vegetables. The prevention and control recommendations are as follows:

1.After the disaster, vegetable root rot, soft rot, gray mold, etc. are very easy to occur, and protective fungicides and fungicides can be mixed with high-quality fungicides.

2.For lepidopteran pests, thrips, and whiteflies, emamectin benzoate, spiroethyl ester, ethyl spinoxin, etc. should be sprayed for control, and brassinolide should be sprayed to supplement nutrition.

What pesticides to use to prevent dead vegetables after heavy rain.

After the rain and flood disaster, the high temperature and humidity of the field environment are prone to a variety of diseases of vegetables. Prevention and control of Jianwu Sui discussion such as the difference between the following words: 1

After the disaster, vegetable root rot, soft rot, gray mold, etc. are very easy to occur, and protective fungicides and fungicides can be mixed with high-quality fungicides. 2.For lepidopteran pests, thrips, and whiteflies, emamectin benzoate, spiroethyl ester, ethyl pedoxyxin, etc. should be sprayed for control, and brassinin qingdonglactone should be sprayed to supplement nutrition.

Is it good to use more information about what kind of medicine to use?

The rollable disadvantage type is irrigated with the roots of Oxazalin, etc., and the second irrigation is done at an interval of 7 days. It can also be used to use any one or two of the fungicides such as Lusujing, ethylphosphine aluminum, and alum, which can be used to prevent and control Buqiao fog. Oh,

If it rains every day and causes vegetables to rot, there are several countermeasures to consider:

1.Do a good job of storage: Store vegetables in a dry, cool place and avoid exposure to moisture. Consider using a breathable container or packaging to help absorb excess moisture.

2.Enhanced cleaning and preservation: After buying or picking, wash the vegetables in a timely manner to remove dirt and impurities, and then dry the water. Vegetables can be wrapped in clean paper towels to absorb moisture, and placed in the wide compartment of the vegetable freshness dust room of the refrigerator.

3.Sorting and handling: Vegetables are inspected regularly and parts showing signs of decay are removed to prevent rot from spreading to other healthy portions. Dispose of rotten vegetables in a timely manner, with the option of composting or discarding them.

4.Adjust the purchase and consumption plan: Adjust the purchase and consumption plan appropriately according to the weather conditions and the shelf life of the vegetables to avoid waste caused by buying too much at one time.

5.Planting moisture-resistant strains: When planting vegetables, choose varieties with strong moisture resistance to reduce the problem of rotting and brightness caused by high humidity in the weather.

Please note that these are some common coping measures, which may vary depending on the type of vegetable, storage environment, and weather conditions. For specific kinds of vegetables, it is advisable to refer to the relevant planting guide or consult a professional for more specific advice.

There are three common diseases of cabbage leaf rot: stem base rot, gourd rot and leaf rot.

The following medicines can be used**Chinese cabbage leaf rot disease:

1. You can choose 2000 times of 72% agricultural streptomycin sulfate soluble powder or 2000 times of neophytomycin, spray 1 time every 7 days, and spray 2 3 times in a row.

2. Soft rot bacteria like alkaline environment, and vinegar can be added during prevention and control.

500 800 ml per mu is conducive to improving the disease resistance of plants.

3. Add 50 kg of water with 100 150 grams per mu of vegetable Fengling, spray 1 2 times or drip into the vegetable field with 751 liters per mu with agricultural resistance.

High temperature and rainy weather, vegetable field management technology requirements are higher, to strengthen the vegetable field drought and flood control, top dressing, weeding, flower and fruit protection and pest control, etc., the management skills and methods of various vegetables are introduced as follows:

Tomato should be properly controlled in the early stage of fertilizer and water, and topdressing should be carried out in time after fruit set, and attention should be paid to the prevention and control of early blight, cotton rot, virus disease, aphids and cotton bollworm.

Eggplant regenerationEggplant should strengthen fertilizer and water management, keep it moist, and focus on strengthening the prevention and control of Verticillium wilt, cotton rot, brown streak, etc. Autumn eggplant or autumn delayed eggplant, about 10 days after planting, fertilizer and water management must be strengthened. In times of drought, it is irrigated with fertilizer and drained immediately after heavy rain.

The focus of autumn cucumber is on the control of pests and diseases. 2 When 3 true leaves, spray with medicine every 7 days to prevent downy mildew. 3 For 4 true leaves, spray 40 ethephon (at a concentration of 100 mg liters) twice and once every 2 days.

The key to zucchini is to prevent and control the occurrence of viral diseases, and attention should be paid to the prevention and control of aphids in the early stage of growth. After the rainstorm, the ditch should be cleaned and the fertilizer should be replenished. Diligent tillage, especially after watering, top dressing and rain, should be cultivated once in time.

From the end of August to the beginning of September, the wilted old vines should be pruned, 1 2 strong side vines at the base should be selected, and the decaying human and animal manure with a concentration of 30 should be applied and the soil should be kept moist.

Winter melon crawling winter melon and winter melon on the shelf can be combined with drought resistance in the middle of growth, and the concentration of 30 rotting human and animal manure and urine can be applied 3 times. Climbing to cultivate winter melon, using seepage ditch irrigation to resist drought, but can not flood irrigation, keep the surface slightly wet. The melon surface cover grass is sunscreen, and the melon bottom cushion grass is anti-rot and insect damage.

When the loofah is high temperature and drought, watering is adopted. After the rain, it is necessary to clear the ditch and drain the stain in time, and it is best to use well water or deep river finger macro stove water to water the ground, so as not to wilt the melon leaves after the rain and affect the fertility. Carry out topdressing and watering in time, and after heavy rain, it is necessary to cultivate in time to prevent and control pests and diseases.

Before flowering and poding, cowpea is mainly cultivated and squatting seedlings, and the soil is kept moist after poding, and the manure is applied once every 2 or 3 times during the full harvest period. The main vine should be topped in a timely manner, and the lower yellow old leaves should be removed in time, and the prevention and control of rust should be paid attention to.

Summer Chinese cabbage and early autumn Chinese cabbage pay special attention to the occurrence of soft rot, Spodoptera litura, and other pests and diseases. After planting and before the live tree, it should be watered in the morning and evening to resist drought and protect the seedlings from seepage. Before and after the rosette period, water frequently to keep the soil moist. At the beginning of the wrapping, pay attention to watering to resist drought.

Early autumn radishes keep the soil moist and water in time for drought. Special attention should be paid to the prevention and control of pests and diseases in the early stage, and the main prevention and control of jumping beetles after the emergence of seedlings, and the timely prevention and control of aphids after the emergence of true leaves. In late August, spray 90 trichlorfon 800 times and 80 ethylphosphine aluminum 400 times to control other pests and downy mildew.

Celery should pay attention to the use of shade nets or straw curtains to build shade shelters in time, strengthen top dressing and watering, and keep the soil moist. Timely control of aphids, soft rot and leaf spot.
