Summary of the invention

Technical problem to be solved by this invention is to provide a kind of walnut pest control method, and the method can solve in walnut process of growth the problem being subject to the harm of disease worm.

In order to solve the problem, the technical solution adopted in the present invention is: this walnut pest control method, comprises the following steps:

A, when young sprout rudiment turns green, spray rudiment with dichlorvos 700 doubly to 800 times liquid;

B, during annual May to August, fruit tree to be generally investigated by strain, and lunge worm channel with iron wire, be then injected into worm channel with dichlorvos 00 doubly to 800 times liquid, and seal worm channel;

C, annual winter remove disease branch, deadwood, and concentrate and burn; At fruit tree their early stage, with thiophanate methyl 700 doubly to 800 times liquid or carbendazim 700 doubly to 800 times liquid fruit tree sprayed 2 times to 3 times or with P applied levels 800 doubly to 1000 times liquid, 1 time to 2 times sprayed to fruit tree.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

The present invention effectively can prevent the damage by disease and insect of walnut, keeps walnut robust plant, and growth situation is excellent throughout the year, and output exceeds 25% than traditional cultivation method.
