The hot fogging concentrate of the invention has the advantages of convenient preparation, low cost, high rain flushing resistance, excellent medical effect, long continuing efficacy, high work efficiency, capabilities of reducing environmental pollution, improving utilization ratio of farm chemical, reducing usage of farm chemical, and adaptability for spraying of hot fog machine.
Description
Technical field
The present invention relates to first dimension salt (active ingredient I hereinafter referred to as) and chlopyrifos (active ingredient II hereinafter referred to as) and be the thermal fog and preparation method thereof of the binary Pesticidal combination of active ingredient, 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 acts on γ-An Jidingsuan, disturbs the activity of insect neurophysiology.Insect is not easy to develop immunity to drugs, and insect is had very strong stomach toxicity and action of contace poison, does not have interior absorption, but can effectively penetrate into the epidermal tissue of crop, and resistance of rainwater washing against has the long 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 higher activity.
Chlopyrifos as active ingredient II is an organophosphorus insecticides, have tag, stomach toxicity and fumigation action, no 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 that 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 does not appear in the newspapers both at home and abroad.
Two kinds of mixing active ingredients proportionings are I: II=1: 10 to 1: 600, be preferably 1: 10 to 1: 200 composition.
Thermal fog is a kind of the former medicine of active ingredient to be dissolved in the solvent with suitable flash-point and viscosity, adds the preparation that other compositions are modulated into certain specification again.In use,, this preparation is sent in the fireworks pipe quantitatively, mixes spraying in the atmosphere with the thermal current of high temperature and high speed, form micron-sized mist or cigarette by means of fog machine.In use because the diffusion of little droplet oneself in the field disperse, after crop or pest contact, sticks to crop or pest surface rapidly.Because the character of finish makes it be difficult for being rinsed out from crop surface by rainwater, help the performance of drug effect simultaneously.Experiment statistics finds that the thermal fog droplet has 10～12 meters diffusion breadth in the field, therefore do not need all to be sprayed onto soup as the every strain crop of traditional application method, thereby improve delivery rate greatly when dispenser.The fogdrop diameter that adds thermal fog is little, and light specific gravity permeates with air-flow easily in air and prevents and treats the position.
The thermal fog spray technique has the following advantages:
Area or some hills and mountain area in arid, the crop of these main plantations in area has corn, sugarcane, the contour bar grain of cassava, economic crops, also have large fruit tree, economic forest or the like in addition, subject matter has lack of water, with a varied topography etc. during with traditional method dispenser in these areas, often there is quite long distance at the water source in the time of prevention and elimination of disease and pests from the dispenser place, add with a varied topographyly to make that efficient is very low dispenser the time, and leak spray easily and reduce control efficiency.And the use of thermal fog and hot mist machine can improve the efficient of prevention and elimination of disease and pests greatly, does not at first need to convert water during dispenser, solves the seek sources of water problem saving of work and time of difficulty of some areas; Secondly hot mist fill the air nature, evenly, only need get final product during dispenser by specific route walking, whether the direction, the dispenser that need not will take into account shower nozzle as traditional application method put in place or the like, reduce the complexity of operating, and increase work efficiency; The ultra-fine droplet preventive effect of hot once more mist machine is good, forms droplet after the dispenser and fully fills the air between crop, has extremely strong penetration power, increases the probability that contacts with insect greatly, 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 above 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 need not to convert water, makes agricultural chemicals availability height, 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 back lasting period.Droplet is high adsorption capacity on crop, and comprehensively evenly, dispenser efficient height, and it is firm that agricultural chemicals adheres on leaf, resistance of rainwater washing against, and the high boiling solvent in the finish can effectively delay the degraded of pesticide active ingredient, and drug effect is permanent.
4. the work efficiency height is prevented and treated in time.The hot mist machine of backpack per hour can spray 20～30 mu.Particularly the control 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 be difficult for to produce poisoning to crop, does not have obviously residually, can improve the quality of crop.
Summary of the invention
The purpose of this invention is to provide a kind of is the thermal fog preparation of active ingredient with first dimension salt and chlopyrifos binary composition.
Another object of the present invention provides the preparation method of described this thermal fog.
This thermal fog comprises the component of following weight proportion:
