When is the right time to apply the first round of spray to peanuts?

As we all know, peanuts need to be sprayed during their growing period, so when should the first round of spray be applied to peanuts?

1. When should the first round of spray be applied to peanuts?

The first round of spray is applied from 15 days after the peanuts emerge to the beginning of flowering. Spraying the peanuts during this period is to prevent and control diseases or other problems in peanuts, such as leaf spot, bacterial wilt, dead seedlings, root rot, etc.

2. What are the three rounds of spray for peanuts?

The three rounds of spray for peanuts are actually a package of pesticides, including three types of pesticides with different functions, namely: nutritional pesticides, growth-regulating pesticides, and fungicidal pesticides, among which:

1. Nutritional pesticides mainly include brassinolide, monopotassium phosphate, ammonium molybdate, trace elements, iron, manganese, zinc, boron, etc.;

2. Growth-regulating pesticides mainly include paclobutrazol, uniconazole, mepiquat chloride, chlormequat, etc.;

3. Fungicidal pesticides mainly include hymexazol, difenoconazole, propiconazole, carbendazim, tebuconazole, etc.

When not in use, the pesticides should be stored in a cool, dry, and ventilated place. If the pesticides are found to have caked, there is no need to worry too much, as this does not affect their effectiveness; they generally dissolve upon contact with water.

If you do not know how to prepare the three rounds of spray, you can buy the three rounds of spray already prepared by the manufacturer. They are generally sold in pesticide stores, and you just need to follow the instructions when using them.

When using the three rounds of spray for peanuts, you also need to pay attention to temperature and light. Generally, spray before 10 a.m. and after 4 p.m. If it rains after spraying, you need to spray again.

3. When is the best time to use the three rounds of spray for peanuts?

1. Best time to use the first round of spray for peanuts: use during the peanut seedling stage for the best effect.

2. Best time to use the second round of spray for peanuts: start using during the peanut pod-setting stage (when 50% of the plants show chicken-head-shaped young pods).

3. Best time to use the third round of spray for peanuts: use during the peanut full-pod maturity stage (twenty days before harvest).
