Leaf fly is traped;Wild wormwood artemisia, which is stacked, in field traps cutworm;Cleaning rural area in time, weeds and crop residues are thorough
Bottom is cleaned out;Manually arrest pest;It can be drained in time when can supply water in time when non-irrigated, is flooded;
3. biological control method
Pest is eliminated using beneficial organism, such as: cabbage butterfly is killed by the parasitic wasp (braconid wasp) in protection base
Larva can reduce harm of the cabbage caterpillar to brassicaceous vegetable;
4. medical treatment method
The organic agricultural chemicals and biological insecticides authenticated using Organic certification structure;It is first in cucurbits powdery mildew, downy mildew morbidity
Phase can spray sulphur powder or Bordeaux mixture on crop, primary every sprinkling in 15~20 days, continuously spray 2~3 times, can be effective
Control disease sprawling;It is prevented and treated using the organic agricultural chemicals crossed by Organic certification agency qualification.
Pest control method of the invention, using weak link of the pest and disease damage in occurrence and development, analysis is formulated corresponding
Control measure, so that crop is got bumper crops good harvest, reliable in quality is stablized.
Specific embodiment
The present invention is made of pest control and disease control two parts, and two parts are implemented simultaneously in insect control, wherein institute
The pest control stated includes cultural control method, physical control method and biological control method:
1. pest control
1.1 cultural control methods
Efficent rotation: according to the variety classes shifting cultivation of vegetables, make to lack food with the pest that single kind crop eats
Object creates the environment for being unfavorable for its existence, mitigates the generation of insect pest;It grasps the pests occurrence rule of pest: fully understanding the hair of pest
Raw rule, appropriate adjustment sowing time make crop growth period be staggered pest damage peak period, achieve the purpose that insect prevention;Intertillage in due course
Weeding, cleaning rural area: the tillage and weeding in due course to organic base, cleaning rural area can will be attached to weeds, the pest on stubble
And worm's ovum cleans out rural area together, to mitigate the harm of pest;Winter ploughing solarization is cut down: every time after harvest, will be had using big machinery
Machine field is ploughed deeply, and the pest for ensconcing underground, ovum, pupa can be made to translate on the ground, on the one hand manually can pick out in this way, another
Aspect can use winter arctic weather and freeze to death part worm's ovum, pupa, achieve the purpose that coming year insect pest mitigates;Select pest-resistant product
Kind: a kind of extent of injury of the same pest on crop is possible to different, this is because between kind caused by performance.Pass through selection
Pest-resistant cultivar can achieve the effect for mitigating pest damage;
1.2 physical control methods
Using the phototaxis of pest, frequency ventilating type insecticidal lamp is installed, adult is traped, can reduce the harm journey of next year
Degree;Using the color that becomes of pest, yellow haftplatte is set, aphid and Liriomyza are traped;Using the good feeding habits of pest, in field
It stacks wild wormwood artemisia and traps cutworm in the edge of a field;Manual catching and killing: according to the inhabiting of pest, egg-laying pattern and special life habit,
