How to Spray Pesticides before Bagging Pear Trees

   Fruit farmers began bagging pears in the middle and late May. At this time, pears were in the young fruit stage, the temperature was higher, and all kinds of diseases and insects also entered the peak period. Therefore, the key to the management of pear orchards before bagging is to control pests and diseases.

How to Spray Pesticides before Bagging Pear Trees

1. Spraying insecticides and fungicides:
In order to prevent diseases and insect pests harmful to fruits such as rot blight, Black Star disease, Tenebrio molitor and Pink scale from being put into bags, insecticides and fungicides must be sprayed strictly before bagging. Here we should pay attention to the selection of high-efficiency insecticides and fungicides which are not easy to cause pesticide damage. Fungicides should be both protective and therapeutic. Foxin or diniconazole can be used as therapeutic agents. Dasheng, Yibao and Daisen manganese and zinc can be used as protective fungicides.

2. Notes:
Fruit growers should pay attention to the following points when spraying medicine before bagging: young fruit surface is tender, water-based agent, suspension agent or wettable powder should be selected as far as possible before bagging, so as not to damage fruit surface;

Using low volume or ultra low volume spray, spray atomization is good, and spray is meticulous and thorough.

Focus on spraying fruit surface, but the sprinkler distance from the fruit surface at least 30 cm, otherwise the pressure is too high, easy to cause fruit surface rust or pesticide damage;

After spraying, bagging should be carried out after the liquid is dried. It is strictly forbidden to bagging before the liquid is dried. Otherwise, it is easy to cause drug damage. A single spraying can bagging for 2-3 days, and the effect will be greatly reduced after 2-3 days, so bagging can be sprayed at the same time. If there is heavy rain in one week or during bagging, it should be re-applied before bagging.
