What medicine should be used to control pear psyllids

1. What medicine to use

Pear psyllid is a common pest that mainly harms trees such as pear trees. If it is not controlled and prevented, it will harm the trees, causing the leaves to dry up and fall off, and will also affect the yield and quality. If the year is very dry, the situation will be more serious. There are many types of drugs used for prevention and control, such as aphidone, spirotetramat, avermectin, muwant, nicotine-matrine, avermectin-mineral oil emulsifiable concentrate, etc. They can also be used in combination with the same good results. You can buy them according to your needs.

2. Medication period

1. The first prevention and control period is the hibernation period, which is around March in the local area. The adults and eggs of this insect will appear on the branches. At this time, conventional pesticides can be used, and the effect is relatively good.

2. After that, the first generation of nymphs will be used for prevention and control. At this time, some overwintering insect eggs will hatch in large numbers, and the use of drugs can kill most of the insects.

3. The later stage is the first generation of adult control, which is a critical period for early control. It can kill more than 90% of the insects. At this time, the flowers just begin to fall, and the adults are just about to begin to emerge.
