As the old saying goes, "Moisture makes diseases sick and drought brings insects." How to manage wheat after rain? These things must be done well

Today is April 25th. I believe everyone has not seen the sun for several days. Many areas have experienced continuous rainy weather. Many friends are worried about how to manage wheat after the rain? What should I pay attention to? Today I will talk to you about wheat field management and precautions after rain.

First of all, disease prevention and control must be carried out in a timely manner. As the old saying goes, "Moisture makes diseases worse, and drought insects bring about diseases." After rain, the humidity in the field will be relatively high. In addition, the temperature will gradually rise. The high temperature and high humidity conditions are very conducive to the spread of diseases. The occurrence and outbreak of wheat scab, powdery mildew and other diseases will also occur earlier this year.

As for pests, they mainly include aphids, midges, etc. Due to the scouring effect of rain and continuous low temperatures, their development progress will be delayed, so pests will be younger than usual and occur slightly later. Even so, , but we should not take it lightly. While preventing and controlling diseases, we can use pesticides, foliar fertilizers, and regulators together. While preventing and controlling diseases and pests, we can also prevent dry and hot winds, provide nutrients, increase the thousand-grain weight of wheat, and ensure an increase in wheat yield.

Regarding the selection of agents, the fungicides can be epoxiconazole, tebuconazole or epoxiconazole, etc. These agents are all compound agents, and many diseases can treat each other, so The effect is still good. As insecticides, you can choose thiamethoxam, thiamethoxam, and chlorpyrifos. These compound drugs are also effective. Brassinoids can be used as regulators.

For foliar fertilizer, you can choose the "old partner" potassium dihydrogen phosphate, and the dosage is 50 to 100 grams (if drone spraying is used, 40 grams per acre is enough). Speaking of unmanned The drone here reminds everyone that it is best to choose instant potassium dihydrogen phosphate when using a drone.

In addition, if you have used boron fertilizer once in the previous period, you can add some boron fertilizer this time (amount of 15~20 grams). Note that boron fertilizer can only be used this time. Do not spray it again when entering the grouting period. Twice.

Someone may ask how much pesticide and fungicide should be used? Since there are many types of insecticides, you can reasonably arrange the dosage according to the variety you purchased and according to the regulations above. As for when to fight? You can take the medicine after it stops raining (you must always pay attention to the weather). According to the weather forecast, it will stop raining tomorrow. After the rain stops, everyone can just take the medicine in time.
