Many people don t know about broccoli poison, what is the good way to kill broccoli medicine?

Introduction: In the process of crop planting, the harmful method is a more commonly used method to make crops grow stronger. There is broccoli in the plants that are often planted by farmers now, so how many people do not know how broccoli is harmed, and they don't know whether it is good or bad for the growth of plants?

1. The period when broccoli growsThe growth period of broccoli generally includes seedling stage, vegetative growth period, flower bulb growth stage, and flowering and seed setting stage. During the vegetative growth period, the plant needs sufficient nutrients to accumulate more assimilated substances and lay the foundation for the development of flower bulbs. Therefore, at this time, broccoli is very prone to pesticide damage.

Therefore, at this time, we need some technology to mix medicinal solutions reasonably and scientifically to deal with the key points of broccoli, so that broccoli can grow better. <>

2. The time of application of the liquid medicineWhen broccoli is growing, especially in the middle of the day, it is the least suitable solution. In the middle of the day when the sun is strong, if the liquid medicine is applied, the resistance of the crop will be reduced under high temperature, and it is not conducive to the healthy growth of the plant, and it is not conducive to the growth of organic vegetables, so it is not possible to choose the liquid medicine at the high temperature at noon. We should apply the potion when the temperature is not particularly high and the sunlight is not strong is the best choice.

Third, the choice of pesticidesWhen using pesticides, it is necessary to strongly and formally select pesticides that meet the national standards. In this way, we can ensure that more organic vegetables are cultivated when growing broccoli, which will also reduce the damage of pesticides to broccoli and ensure that the flowers grow healthier. This is also responsible for consumers and the sense of responsibility for businesses, and at the same time, it is also in line with the development requirements of the contemporary environment.

Do not pollute the environment, and seek maximum economic benefits in the organic environment, so the above are some of the better ways to harm broccoli.

It is also possible to minimize this critical situation by replacing the soil or watering more, cultivate a better environment, or choose to spray other chemicals to reduce the damage of pesticides.

You can choose some mixed liquid to spray it, and you can choose the time of the pharmaceutical industry, preferably in the afternoon, so that it can recover quickly, and when choosing pesticides, you should still choose some pesticides with less damage, and you can regularly fertilize them to ensure sufficient sunlight to kill pests, and you can also better protect broccoli.

First of all, we should choose pesticides that are safe for crops, and try to avoid applying pesticides during the period when crop resistance is weak. Special attention should be paid to spraying pesticides at the seedling stage and flowering stage, and the pesticide application technology should be correctly mastered, and fertilization should be carried out in strict accordance with the specified concentration and dosage.

The most common control methods are the use of pesticides, reduced fertilization, the use of trace elements, and pesticides, which can lead to the most common pests and diseases.

Answer broccoli pest 1, downy mildew symptoms. It is a disease, which is more obvious in the process of flower bulb development, the old leaves first develop the disease, and then spread to the young leaves, and the lack of green in the early stage of the disease, and the leaves turn yellow. When dry, the leaves dry out, and when wet, mold appears on the back of the leaves.

2. Symptoms of soft rot. It is a disease, and broccoli is prone to occur when it encounters more rain in the later stage of growth. The lesions are water-stained, gradually softening and decaying, producing a foul smell; Germs invade from wounds on roots, stems, and leaves.

3. Diamondback moth symptoms. The first instar larvae can only feed on the mesophyll, leaving a transparent epidermis, and the 3-4 instar larvae can eat the leaves into holes, and in severe cases, the whole leaves are eaten into a net. 4. Symptoms of cabbage worm.

The larvae eat the mesophyll, leaving only a layer of transparent epidermis, and only leaf veins are left, which is prone to soft rot when harming the flower bulbs, and insect feces will also pollute the flower bulbs and reduce the value of the commodity. 5. Symptoms of vegetable aphid. The damaged plants are seriously dehydrated, shrinking, yellowing, twisted and deformed, and the damage of vegetable aphid can also cause soot disease and spread virus diseases.

Broccoli disease and pest control method 1, downy mildew selection of varieties with strong disease resistance. Avoid continuous cropping, the soil should be turned deep and whitened, and an appropriate amount of lime should be applied to improve. At the beginning of the disease, spray with 600-800 times of 70% mancozeb wettable powder, or 400-600 times of methamphene.

Stop using pesticides 10-15 days before harvesting. 2. Soft rot. Avoid co-cropping with cruciferous vegetables, especially cabbage and cabbage.

Strengthen field management and cultivate strong seedlings. Avoid injuries and pay attention to drainage after rain. At the beginning of the disease, spray streptomycin sulfate, or 72% agricultural streptomycin wettable powder 3000-4000 times, or new phytomycin 4000 times.

3. In the early stage of the disease, diamondback moth is used to trap and kill adult insects with black light. It can also be sprayed with 500-1000 times of Bacillus thuringiensis preparation, or 1000-2000 times of 50% phosphine emulsifiable concentrate. Stop using pesticides 10 days before harvesting.

4. In the early stage of the disease, spray with BT emulsion, or 500-800 times of No. 6 liquid of green worms, or 1000 times of 50% phoxanthion emulsifiable concentrate, or 3000-4000 times of 20% fenvalerate emulsifiable concentrate. If it rains after spraying, it should be sprayed. Stop using pesticides 10 days before harvesting.

5. Rapeseed aphids are set up in the broccoli field to attract aphids, and the yellow board is 8 pieces per mu. Hang silver-gray membrane strips to avoid aphids, the membrane width is 12-23 cm, and the height is less than 1 meter. At the beginning of the disease, spray with 40% dimethoate 1000 times, or acetamiprid 40% (water dispersible granules) 1000-2000 times.

Stop using pesticides 15 days before harvesting.

First of all, when planting, we must choose the soil is more fertile and wide land, and we must use farmhouse fertilizer when fertilizing, do not use fertilizer bought outside, and also often water the plants, but also often prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time. I think that if we can do these things well, we will definitely be able to control broccoli pests and diseases.

It should be that some pesticides can be sprayed during the growth process of broccoli, and it should also be noted that some rotten or yellowed leaves must be pruned off in time.

They use pesticides to control pests, or to understand the situation of pests and diseases, or to use physical control methods, or to place pest removal products around them.

Hello, I am glad to answer for you The main diseases are downy mildew, soft rot, black rot, anthracnose, etc. For downy mildew, 75% chlorothalonil wettable powder 500 600 times liquid, 722% Pulik water agent 600 800 times liquid, 64 alumucible wettable powder 400 times liquid spray control.

Soft rot and black rot can be sprayed with 72% agricultural streptomycin sulfate 3 000 4 000 times or 77% can kill 500 times liquid. Anthrax can be prevented and treated by spraying 1 500 times of 10% Shigao water-dispersible granules.

Broccoli root swelling disease, what pesticides are used to have special effects, broccoli to root swelling disease.

Hello, glad to answer for you. <>

Fiber prevention and treatment method of broccoli root swelling disease: prevention and control of root swelling disease, the use of root boy compound microbial fertilizer for prevention and control, can be foliar spraying can be used for root irrigation. Considering that root swelling mainly occurs in the underground part, it is better to irrigate the roots after water dissolution of root boys.

Medicinal fertilizer preparation for the prevention and control of root swelling disease, the prevention of the use of the recommended concentration can be flushed, the prevention and control of the recommended concentration of the root irrigation, the effect is better. It should be noted that the occurrence of broccoli root swelling disease can be spread through rainwater, irrigation water, insects and farm tools, and the bacterial soil, acidic land, and high humidity environment are the climatic basis for the epidemic of root swelling disease.
