The three rounds of peanut spray is a relatively important peanut pesticide, named “three rounds of spray” because it is applied a total of 3 times, so when should the first of the three rounds of peanut spray be applied?

1. What is the three rounds of peanut spray?

The three rounds of peanut spray is actually a package of pesticides, including three pesticides with different effects, namely: nutritional pesticides, growth-control pesticides and fungicidal pesticides, among which:

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

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

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

If you do not know how to mix the three rounds of spray, you can buy the three rounds of spray already mixed by the manufacturer; it is generally sold in pesticide shops, and you just need to follow the instructions when using it.

2. When should the first of the three rounds of peanut spray be applied?

The first round of peanut spray is applied during the period from 15 days after the peanut seedlings emerge to the beginning of flowering. Spraying during this period is mainly to prevent and control peanut seedling death, root rot, or infection by some diseases, such as leaf spot disease and bacterial wilt, etc.

The second round is used from the full flowering stage to the pod-setting stage of peanuts, mainly to control excessive growth, intelligently regulate nutrient distribution, and prevent peanuts from growing too vigorously.

The third round of spray is used 20-30 days before harvest, in order to suppress diseases such as leaf spot disease and rust disease, and prevent premature aging and leaf drop.

3. Precautions for using the three rounds of peanut spray

1. When the pesticide is not in use, it should be stored in a cool, dry, ventilated place. If you find that the pesticide has caked, do not be too nervous; this does not affect the effect, and it generally dissolves upon contact with water;

2. When using the three rounds of peanut spray, 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 as a supplement.
