Pear tree pests and their control

Pear Tree Pests: Pear Star Caterpillar

This insect is a major leaf-feeding pest of pear trees. Its larvae damage leaves, flower buds and flower buds twice a year. The prevention and control measures are as follows:

1. Prevention and control are usually carried out once in March-April and once in August-September.

2. You can use common pesticides such as 1000 times diluted 50% phoxim emulsion, 3000 times diluted 20% cypermethrin emulsion, 1000 times diluted 50% malathion emulsion and 1000 times diluted 50% carbofuran emulsion for spraying and prevention.

Pear tree pests: Pear Shifeng

It is also commonly known as flower drill and white drill. This insect only harms pear trees, usually in mid-to-late May, with the larvae causing damage by eating into the fruit. One generation is produced per year, and the adults emerge and lay eggs between April and May. The peak egg-laying period of Pear Peak is when the inflorescence of the pear tree separates into buds ready to bloom. Specific prevention and treatment are as follows:

1. Take advantage of the adult's characteristic of feigning death, put a sheet under the crown of the pear tree, shake off the adult and kill it;

2. During the egg-laying period of Lishifeng, remove the fruit with eggs and young fruit with insects manually;

3. About 10-15 days before the pear tree blooms, when the adult insects are about to emerge from the soil, you need to use 300 times diluted 25% parathion. You can also choose 600 times diluted 40.7% Lorsban emulsifiable concentrate and other agents to control it by ground spraying, focusing on the area within 1 meter around the tree trunk.

Pear tree pests: Pear psyllid

The insect can cause damage to the leaves and tender shoots of pear trees, and can also induce sooty mold, causing the pear trees to drop leaves and fruits, and the fruit quality to deteriorate, which has a significant impact on the pear tree's yield. Prevention and treatment are as follows:

You can use 1250-1500 times of Insect Mite Gram, or 3000 times of Kangfuduo for prevention and control.
