A kind of composition pesticide preventing and treating cotton red spider disease
Technical field
The present invention relates to a kind of composition pesticide preventing and treating cotton red spider disease, belong to agricultural technology field.
Background technology
Cotton red spider is the insect on cotton.Death of seedling, fruit abscission rate can be caused, bell heavily alleviates, output reduce.Easily there is insect pest in it non-irrigated hot weather.Chrysopa in cotton field, Stethorus chengi etc. have good inhibitory action to it.Also available sulphur deflocculant, Dicofol emulsion etc. are prevented and treated it.The tetranychid general name cotton red spider of harm cotton.If the one-tenth mite of cotton tetranychid all draws juice at cotton leaf back, chlorophyll variable color, when general a slice leaf having tetranychid less than 5, there is " macula lutea " in blade, occurs " red sand " spot during more than 5, when individuality is more, " erythema " expands, and when being injured serious, blade is shrivelled, finally comes off, seedling killed serious time, cause dead seedling; The cotton buds and bolls phase is injured, and increase fruit abscission rate, bell heavily alleviates, and output reduces.
Cotton spider mites breeding is very fast, and control will be strengthened the process to overwintering host, when cotton field occurs, controls it at a stage of development.1. cultural control (1) hibernacle process: after crop harvesting, concentrates dry branches and fallen leaves in time and burns; Remove ridge, limes marginis, the weeds in roadside and the weeds near limit, cotton field village, graveyard early spring in late fall; Pay attention to the autumn and winter and plough deeply ground, and carry out winter irrigation.(2) to choose seeds anti-mite kind: general seed selection blade lower epidermis is thicker, and the cotton variety that fine hair is longer, unfavorable tetranychid takes food.(3) cotton and beans, sesame and the crop such as melon are tried not intercropping or adjacently to do.Strengthen cotton field water, fertile management, ensure that Cotton growth is good, reduce mite class and cause harm.(4) in conjunction with farming operation, timely thinning, final singling, pulled out mite seedling, and focused in time.2. perform five word policies of mite class control in field, namely " look into, insert, pluck, smear, beat " and look into: look into killed strain; Insert: find that mark is plugged in killed strain; Pluck: extracing cotton plant bottom has mite blade, and take cotton field destruction out of; Smear: erase in cotton plant, the mite of top blade back; Beat: carry out chemical control in time.3. chemical control: investigation mite feelings in time, carries out the control of early stage spot film, controls its diffusion.Medicament and use: 50% sulphur deflocculant dilutes 300 times; 20% Dicofol emulsion dilution 1000 ~ 2000 times; 50% nuvacron missible oil and 40% flolimat emulsion dilute 2000 times, and spraying all has good preventive effect.But cultural control and existing chemopreventive effects are obvious not, artificial mite manpower and materials of removing are wasted comparatively large, therefore, need the composition pesticide of the control cotton red spider disease working out a kind of better effects if badly.
Summary of the invention
The object of the present invention is to provide a kind of composition pesticide preventing and treating cotton red spider disease, adopt natural Chinese medicinal herb composition, draw materials conveniently, use simple and easy, the sick effect of control cotton red spider is better.
