Description
Technical field
The present invention relates to thermal fog of the binary Pesticidal combination that first dimension salt (hereinafter referred to as active ingredient I) and chlopyrifos (hereinafter referred to as active ingredient II) are active ingredient and preparation method thereof, belong to the pesticidal preparations field.
Background technology
First dimension salt as active ingredient I belongs to new and effective, broad-spectrum antibiotic class insecticidal/acaricidal agent, and the mechanism of action uniqueness, act on γ-aminobutyric acid, disturbs the activity of insect neurophysiology.Insect is not easy to develop immunity to drugs, and insect is had to very strong stomach toxicity and action of contace poison, without interior absorption, but can effectively penetrate into the epidermal tissue of crop, and resistance of rainwater washing against, have the longer lasting period.Insect to biting mouthparts and sucking mouth parts all has good preventive effect, and mite class, coleoptera and homoptera pest are also had to higher activity.
Chlopyrifos as active ingredient II is organophosphorus insecticides, have tag, stomach toxicity and fumigation action, without systemic action.Can be used for preventing and treating rice leaf roller, rice thrips, rice gall midge, rice fulgorid, rice leafhopper, the wheat mythimna separata), aphid, vegetables cabbage caterpillar, diamond-back moth, lima bean pod borer, tea geometrid, the thin moth of tea, tea caterpillar etc., and livestock vermin and soil insect.
The existing preparation of the binary Pesticidal combination the present invention relates to mainly contains missible oil, aqueous emulsion, microemulsion and wetting powder etc.And the thermal fog of first dimension salt and chlopyrifos binary composition has no report both at home and abroad.
The mixing match of two kinds of active ingredients is I: II=1: 10 to 1: 600, be preferably the composition of 1: 10 to 1: 200.
Thermal fog is a kind of the former medicine of active ingredient to be dissolved in the solvent with suitable flash-point and viscosity, then adds the preparation that other compositions are modulated into certain specification.In use, by means of fog machine, this preparation is sent in the fireworks pipe quantitatively, with the thermal current of high temperature and high speed, mixes and spray in atmosphere, form micron-sized mist or cigarette.In use due to the diffusion of little droplet oneself in the field disperse, after crop or pest contact, stick to rapidly crop or pest surface.Due to the character of finish, make it be difficult for being rinsed out from crop surface by rainwater simultaneously, be conducive to the performance of drug effect.Experiment statistics finds that the thermal fog droplet has the diffusion breadth of 10～12 meters in field, therefore when dispenser, does not need every strain crop as traditional application method all to be sprayed onto liquid, thereby greatly improves delivery rate.The fogdrop diameter that adds thermal fog is little, and light specific gravity easily permeates and prevents and treats position with air-flow in air.
The thermal fog spray technique has the following advantages:
In arid area or some hills and mountain area, the crop of these main plantations in area has corn, sugarcane, the contour bar grain of cassava, economic crops, also have in addition large fruit tree, economic forest etc., in these areas, subject matter has lack of water, with a varied topography etc. during with traditional method dispenser, in the time of prevention and elimination of disease and pests, often there is quite long distance at water source from the dispenser place, add with a varied topography when making dispenser efficiency very low, and easily drain spray reduces control efficiency.And the use of thermal fog and hot mist machine can improve the efficiency of prevention and elimination of disease and pests greatly, at first do not need to be watered during dispenser, solve the problem saving of work and time that some areas seek sources of water difficult; Secondly hot mist fill the air nature, evenly, during dispenser, only need to get final product by specific route walking, without the direction that will take shower nozzle as traditional application method into account, dispenser, whether put in place etc., reduce the complexity operated, increase work efficiency; The ultra-fine droplet preventive effect of hot mist machine is good again, forms droplet after dispenser and fully fills the air between crop, has extremely strong penetration power, greatly increases the probability contacted with insect, gives full play to the control efficiency of medicament.
1. fogdrop diameter is little, is uniformly dispersed, and penetrability is good, has improved the deposition of agricultural chemicals on the target crop, has improved the uniformity of agricultural chemicals deposition.The deposition of agricultural chemicals on crop surface improves and surpasses 30% than conventional spraying, and leaf back side agricultural chemicals deposition is the several times of conventional spraying, and crop top, middle part and root agricultural chemicals deposition distributing homogeneity all are significantly increased.
2. environmental influence is little, has reduced the pollution of agricultural chemicals to environment.The use of thermal fog, without being watered, makes the agricultural chemicals availability high, has avoided agricultural chemicals to run off and contaminated environment with flowing water in the process of diluting and spraying.
3. it is long that thermal fog is used the rear lasting period.Droplet is high adsorption capacity on crop, and comprehensively evenly, dispenser efficiency is high, and it is firm that agricultural chemicals adheres on leaf, resistance of rainwater washing against, and the high boiling solvent in finish can effectively delay the degraded of pesticide active ingredient, and drug effect is permanent.
4. work efficiency is high, and control in time.The hot mist machine of backpack per hour can spray 20～30 mu.Particularly controlling the great outburst insect in period, advantage is more obvious.
5. being particularly suitable for the drought and water shortage area uses.
6. because fogdrop diameter is little, be uniformly dispersed, thermal fog is difficult for producing poisoning to crop, without obviously residual, can improve the quality of crop.
