Description
Technical field:
The present invention relates to the method for preventing and treating of vegetable-crop pest-insect, relate in particular to the method for preventing and treating of aleyrodid on the facility ground vegetables.
Background technology:
Along with the adjustment of pattern of farming, aleyrodid (comprising Trialeurodes vaporariorum Westwood and Bemisia tabaci) is still a kind of important pests on field crop, greenhouse vegetable and the ornamental plant.Two kinds of aleyrodid plesiomorphisms have many common host plants, and normal the mixing takes place in the greenhouse.Aleyrodid inhales water as main take thorn, secretes simultaneously honeydew and brings out mould dirty disease, and Bemisia tabaci also can be propagated the Various Diseases viral disease, has a strong impact on the yield and quality of crop.At present; China still adopts chemical pesticide widely to the control of protection ground vegetables aleyrodid; because the aleyrodid body is by wax; individual small, habit is hidden, and one-tenth, nymph are all got food at blade back; cause dispenser inconvenience thus; particularly, more increased the difficulty of chemical control, reduced control efficiency at vegetables Feng Hanghou such as tomato, cucumber, Kidney beans.In addition; Trialeurodes vaporariorum Westwood and Bemisia tabaci all have very strong pesticide resistance; because prolonged application chemical control in the protection ground; cause aleyrodid that most of conventional dose has all been produced resistance in various degree; not only do not reach the effectively preventing effect; also be easy to cause the outburst of aleyrodid large tracts of land, and then influence vegetable yields and quality, cause serious economy loss.Therefore coordinate to use every effectively preventing measure, become problem anxious to be resolved in the protection ground vegetables.
Summary of the invention:
The object of the invention is to provide the method for preventing and treating of aleyrodid on the cover protection ground vegetables, and this method comprises the steps:
Step 1: promptly and accurately measure insect pest situation, instruct large area control work.
1. five point samplings are adopted in the aleyrodid field investigation, sample is unit with the strain, investigation method is: five sampling points of every canopy chamber (or greenhouse) picked at random, every sampling point investigation strain number is no less than 5 strains, adopt whole strain investigation method, investigation in per 7 days once is advisable with the 4:00～6:00 investigation of every morning 8:00～10:00 or afternoon, record individual plant borer population.
2. use yellow plate to lure integrated worm, grasp adult and take place dynamically.Aleyrodid has stronger chemotaxis yellow habit, can adopt commercially available yellow plate or from manufacture-yellow plate (hardboard is coated with yellowly, is coated with one deck machine oil or insect sticker again), lure integrated worm, grasps adult and takes place dynamically.
Step 2: the insect pest situation of monitoring according to step 1, adopt that to cultivate no worm strong sprout, cover cultural control, the physical controls such as fly net, yellow plate trapping be basic, discharge the coordination of biological natural enemy and chemical pesticide and be controlled to be main body, the control strategy of the effective combination of measures.
1. cultivate no worm strong sprout: cultivating no worm strong sprout, control initial population density, is the key of preventing and treating the aleyrodid success or failure.Winter-spring season is grown seedlings Fang Yaoyu production greenhouse separately, the front removing stubble weeds of growing seedlings, the remaining adult whitefly of smoked kill; Summer and autumn, the ventilating opening place sealed with 30-40 order nylon yarn, cut off external worm source; Concentrate the control of dispenser medicine before the seedling replanting.
2. cover fly net: before the greenhouse vegetable field planting, the cleaning rural area, the ventilating opening place establishes fly net, and the general 30-40 order of grenadine order number helps stoping moving into of small worm such as aleyrodid, aphid to help cutting off its history of life.
3. enhance field management: according to the aleyrodid life habit, aleyrodid nymph and pseudo-pupa mainly concentrate on the plant middle and lower part, and in the vegetable growth phase, in conjunction with field management, training is interrupted, and extract bottom band worm Lao Ye, move to outside the field to focus on; Behind the harvest home, in time remove in the greenhouse the residual branches and leaves with worm, and remove in the greenhouse and around weeds.
4. yellow plate trapping: adult whitefly has stronger the become Huang and the tender habit that becomes, adult mainly concentrates on plant top tender leaf, evenly hang yellow plate after the plant field planting, suspension height is with yellow plate bottom and the plant top is contour is advisable, along with the height of yellow plate is in time regulated in the growth of plant, monitor aleyrodid simultaneously with the trapping adult and take place dynamically.Protection ground hangs 20 for every mu, can doublely control important pests such as Liriomyza and aphid.
5. discharge natural enemy: in protection ground, (average 0.5/when strain is following) begins to discharge Encarsia formosa during adult whitefly generation low-density.Also can when finding adult whitefly on the yellow plate, begin to discharge natural enemy according to yellow plate monitoring situation.Burst size and method: every mu discharges 10,000, discharges once, and discharges 2～3 times in per 7～10 days.The honeybee card evenly is hung in greenhouse, the booth, be hung in the plant, top is advisable.This method is simple to operate, saving of work and time.
6. rationally use agricultural chemicals: use the highly effective and safe agricultural chemicals to coordinate control aleyrodid population density in case of necessity, 6000～8000 times of safe water dispersible granules of available 25% Acker or 30 milliliters/strain root irrigation before the seedling field planting; In the vegetable growth process,, can spray medicament, force down the adult radix, can discharge natural enemy in 5～7 days after the medication, to guarantee the survival and the pest control effect of natural enemy if the aleyrodid radix is excessive.Interchangeable medicament has: 5000～6000 times of the safe water dispersible granules of 25% Acker, 2000～2500 times of 10% imidacloprid wettable powders, 2000～2500 times of 10% imidaclothiz wetting powders, 200～300 times in 99.1% mineral oil.
Compare with existing protection ground conventional chemical administrative skill: advantage of the present invention: 1. prevention effect is stable, is better than tradition and prevents and treats method, and prevention effect can reach more than 85%; 2. significantly reduce labour intensity, simple to operate; 3. reduce the agricultural chemicals access times, reduce the residual and pollution of chemical pesticide, improve the vegetables production environment, improve the yield of vegetables quality.
