Do you know what kind of pesticides are needed for weeding in pepper fields?

Pepper has the effect of warming the stomach, dispelling cold, dryness and dampness, so it is widely planted, and weeds are very common in the process of pepper planting. So what kind of pesticides do you need for weeding in chili fields? How should I choose? We might as well have a look together.

First of all, we need to understand that different pepper fields need different weeding methods and pesticides:

1. Direct broadcast field

The direct seeding field can be sprayed with Shanghai Shanghai Union Shi Tianwang 33% dimethamyl EC 50% 75ml / mu before emergence after sowing. If you want Hekuo Shuangfeng, the above agents should be mixed with 24% ethoxyfluoxane EC 10ml / mu.

However, we should pay attention to the following points: ① strives to level the ground so as to avoid drug damage caused by bare seeds or shallow sowing. ② 30kg / mu 40kg liquid, strive to spray evenly, do not re-spray. The dose of ③ should not be increased at will. ④ tries to watch weather sowing and spraying to avoid drug damage caused by continuous overcast and rain after seedling emergence, and should not be watered before and after emergence. ⑤ for film-covered fields, it is not recommended to spray the liquid directly under the film to avoid drug damage after emergence.

II. Transplanting fields

For transplanting fields, 150,200ml of Shanghai Union Shitianwang can be sprayed 1-3 days before planting. If you want Hekuo Shuangfeng, these agents are mixed with 24% ethoxyfluoxane EC 20ml. However, it should be noted that the soil layer should not be turned as far as possible during the planting operation.

If there are weeds during the growth period, only 10.8% efficient Pyrrolofop EC 20ml 40ml, or 10% oxazolyl EC 50ml 75ml can be used. After 3 leaves of the weeds, the stems and leaves are sprayed to control Gramineae weeds.

III. Medication during growth

If there are weeds during the growth period, only 10.8% efficient Pyrrolofop EC 20ml 40ml, or 10% oxazolyl EC 50ml 75ml can be used. After 3 leaves of the weeds, the stems and leaves are sprayed to control Gramineae weeds.

Secondly, we should pay attention to: 1. Before the disease of hot pepper, or before it rains and prepares to irrigate the land, first spray the protective fungicide 68.75% DuPont easy to protect 1000 times. For the fields with weak seedlings and yellowing leaves, you can add some high-quality foliar spraying fertilizer such as Zhuang, which can be used to supplement the lack of trace elements in plants and prevent the spread of physiological diseases.

Due to the unique rapid germicidal mechanism of Yibao, it is extremely resistant to Rain Water erosion after medication, has a strong ability of redistribution after rain, and does not spray again in case of rain. It has double protective effect and has a longer duration (the protective period is about 12 days). It has a wider germicidal spectrum and is effective against a variety of diseases, so it is no longer necessary to mix other protective fungicides. Continuous use is not easy to produce resistance and contains a variety of trace elements to stimulate the better growth of crops. The utility model has the advantages of low dosage, no medicine trace in the peel, clean appearance and high value of the fruit.

two。 If the spraying time is proper, it is easy to protect pepper by spraying 2 times and 3 times during the whole growth period, which will inhibit the occurrence of other diseases and get excellent control effect.

Why pepper users spray pesticides but the effect is still not very good, the main reason is: the diagnosis of the disease is ambiguous, treat bacterial diseases as fungal diseases, and then choose the wrong way to choose pesticides. Greedy to buy pesticides with not enough active ingredients cheaply, so the effect is poor. Generally speaking, there are few bacterial diseases in pepper field, and most of them are fungal diseases. During the onset period, we can use 40% Fuxing EC 8000-12000 times or 20.67% Wanxing EC 2500 times alternately, which has a good control effect on anthracnose, powdery mildew, Fusarium wilt and other diseases of pepper. If the epidemic disease is serious, 72% Kelou wettable powder can be sprayed 600 times in the initial stage, and 2500 times solution can be used in the middle and later stages.

When spraying fungicides each time, some insecticides such as 2500 times of Wanling or 3000 times of imported kungfu can be sprayed appropriately. If the harm of mites is serious, 2500 times of effective acaricide mites can be sprayed to achieve double prevention of diseases and insect pests.

Good use of medicine can reduce the frequency of drug use and reduce the cost of drug use. You have to prescribe the right medicine to the case. that's the real goal. Advocate the principle of "giving priority to prevention, combining prevention and control, and prevention is more important than cure".
