How to control aphids

Aphids are pests that often destroy farmers' crops. Through investigation, it is found that the harm caused by aphids has certain regularities. Therefore, in the process of preventing and controlling aphids, it is necessary to formulate some reasonable prevention and control plans. Different plans should be adopted for prevention and control according to different crops. Only in this way can the harm of aphids be avoided. Let us learn about this aspect below.

How to control aphids

Through understanding, we found that aphids have different patterns of damage every year, and the methods and plans of using pesticides on different crops are also different, so the prevention and control methods must also be adapted to local conditions. The following plans are a compilation of aphid control plans provided by agricultural technicians in Shandong, Henan and Hebei. Let’s see how they deal with aphids.

We all know that aphids are piercing-sucking insects, so the drugs used against piercing-sucking insects include: acetamiprid, imidacloprid, avermectin, pymetrozine, thiamethoxam, thiacloprid, spirotetramat, nitenpyram, sulfoxaflor, bifenthrin, and spinetoram, etc.

Wheat Aphid Prevention Program

Aphid prevention plan for wheat during the flowering period: imidacloprid + pyraclostrobin + diphosphite + brassinolide (pyrazole has a long prevention time, imidacloprid prevents aphids, and diphosphite supplements nutrition to promote the regulation of nutritional balance) Aphid treatment plan for wheat during the filling period: thiamethoxam + highly effective chlorfenapyr + propiconazole or diniconazole (used to prevent and control wheat powdery mildew and rust) + potassium dihydrogen phosphate + micro-fertilizer (2-3 times of use can have a significant yield-increasing effect) Some compound preparations can be used alternately for the best effect. Note: The causes and patterns of disease vary in different regions. Please make reasonable arrangements based on local conditions. In addition, you must be careful and thorough when killing aphids because aphids can easily lurk on the back of leaves. It takes 5-7 days to apply aphid killer 2-3 times to stop the insects.)

Vegetable aphid prevention program

1.6% cypermethrin + avermectin + silicone + micro-fertilizer 2. When aphids are serious, use: 6% cypermethrin or spinosad (auxiliary use for killing insects, mainly for killing thrips, the cost is a bit high, use it during serious periods, it is better to use it on vegetables). Note: Because of the fear of hurting bees, greenhouse strawberries generally use cypermethrin. If there are no bees in the area, you can use nitenpyram or thiamethoxam; cypermethrin is safer and more reliable.

Aphid prevention program for fruit trees

Treatment plan: 2. Cypermethrin + highly effective cyhalothrin + pyraclostrobin (If the temperature rises, Cypermethrin can be used to treat fruit trees, which is more effective than imidacloprid)
