Description
Technical field
The invention belongs to technical field of pesticide, specifically is the thermal fog of pyraclostrobin-containing and sterol synthetic inhibitor.
Background technology
In the area of arid particularly in hills and mountain area; And forest zone; The problem that mainly can run into when using traditional method dispenser prevention and elimination of disease and pests has: lack of water, with a varied topography, forest is tall and big, instrumentation difficulty etc., efficient is very low, and leaks spray easily and reduce control efficiency.Using of thermal fog has following characteristics:
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 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 back lasting period.Droplet is high adsorption capacity on crop, and comprehensively evenly, dispenser efficient is high, 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. work efficiency is high, and control in time.The backpack fog machine per hour can spray 20～50 mu.Particularly the control large tracts of land outburst insect in period, advantage is more obvious.
5. be particularly suitable for drought and water shortage area and uses such as tall and big forest such as bamboo grows.
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.
The use of thermal fog and fog machine can be in the hills and the mountain area of the efficient that improves prevention and elimination of disease and pests greatly, particularly some lacks of water.Need not convert water during dispenser, solve some areas seek sources of water the difficulty the problem saving of work and time; During use smog fill the air nature, evenly, only need get final product during dispenser by specific route walking, whether the direction, the dispenser that need not as traditional application method, will take into account shower nozzle put in place or the like, reduce the complexity of operating, and increase work efficiency; The ultra-fine droplet preventive effect of fog machine is good, forms droplet after the dispenser and between crop, fully fills the air, and has extremely strong penetration power, increases the probability that contacts with insect, can give full play to the control efficiency of medicament.
Pyraclostrobin is pyraclostrobin again, Chinese: N-{2-[1-(4-chlorphenyl)-1H-pyrazole-3-yl oxygen methyl] phenyl } (N-methoxyl group) methyl carbamate, belong to methoxy acrylic bactericide.It stops the synthetic of cell ATP through the electronics transmission of pinning between cytochrome b and the C1, makes mitochondria can not produce and provide cell eubolism institute energy requirement to cause cell dead.It can control most of diseases such as Ascomycetes, Basidiomycetes, deuteromycetes, Oomycete; Growth to spore germination and leaf intramatrical mycelium has very strong inhibitory action; Have protectiveness, therapeutic and local interior the suction and osmotically active, the lasting period is long, resistance of rainwater washing against.Be widely used in preventing and treating the disease on wheat, paddy rice, peanut, grape, vegetables, potato, banana, lemon, coffee, fruit tree, walnut, tea tree, tobacco, ornamental plants, lawn and other field crops.This compound not only toxicity is low, to non-target organism safety, and also all friendly safely to user and environment, classified as " the candidate's medicament that reduces risk " by U.S. EPA.
At present the sterol synthetic inhibitor has missible oil, suspending agent, microemulsion, wetting powder, a water dispersible granules common on the market; There are long-term single a large amount of uses in this active component; Make germ produce very strong resistance, be unfavorable for the further raising of drug effect, increased the difficulty of bacteria-treating; Need to strengthen dosage and spray medicine number of times, not only improved labour intensity but also strengthened the control cost.In addition, a large amount of uses of medicament must cause the residual quantity of environment to increase, and cause certain pollution to environment.And do not appear in the newspapers as yet both at home and abroad with the composite thermal fog of pyraclostrobin.
Summary of the invention
The objective of the invention is to prevent and treat the technical solution that defectives such as the work efficiency that exists on the method is low, labour intensity is big, water requirement is big propose, the novel thermal fog of a kind of pyraclostrobin-containing and sterol synthetic inhibitor is provided for overcoming conventional spray technique.
The technical scheme that the present invention solves the problems of the technologies described above is following:
The thermal fog of pyraclostrobin-containing and sterol synthetic inhibitor is prepared routine by thermal fog and is prepared by active component, auxiliary agent and solvent composition.
Wherein: active component is by pyraclostrobin and the sterol synthetic inhibitor is composite forms; The weight percentage of pyraclostrobin is 1%～10%; The weight percentage of sterol synthetic inhibitor is 2%～20%, and the sterol synthetic inhibitor is any one in Fenarimol, pyrifenox, flumorph, thiophene fluorine bacterium glue, Grandox fumigant, the pefurazoate; The weight percentage of auxiliary agent is 3%～15%; Solvent supplies 100%.
Above-mentioned solvent is one or more combination of following solvent:
Polar solvent acetophenone, phenmethylol, N-Methyl pyrrolidone, N, dinethylformamide, DMAC N,N, methyl-sulfoxide, the above alcohols of C6 such as n-octyl alcohol; Aromatic hydrocarbon solvent trimethylbenzene, o-dichlorohenzene, the above heavy aromatics of C10, two wires oil; Plant oil such as soybean oil, cottonseed oil, rapeseed oil, castor oil, turpentine oil, esterified vegetable oil such as methyl oleate, ethyl oleate; Phthalate esters; Preferred boiling point is high, flash-point is higher than 80 ℃ solvent.
Above-mentioned auxiliary agent is AEO, APES, phenethyl phenol polyethenoxy ether, alkylaryl polyoxyethylene polyoxypropylene ether, aliphatic alcohol polyoxyvinethene phosphate, APES phosphate, phenethyl phenol polyethenoxy ether phosphate, alkylaryl polyoxyethylene polyoxypropylene ether phosphate, castor oil polyoxyethylene ether, calcium dodecyl benzene sulfonate; Synergy phosphorus, sulfoxide, piperonyl butoxide; Azone, thiophene ketone, ooze one or more combination among the T soon.
Thermal fog of the present invention adopts technical matters preparation known in the art, normally active component and solvent, the abundant stirring and dissolving of auxiliary agent is mixed and forms.
The invention has the beneficial effects as follows:
1, flash-point is high, job safety.It is material that thermal fog product of the present invention adopts high flash solvent, adds special fire retardant, and the thermal fog product flash-point of production is high, in use is difficult for catching fire, high to people and crop safety.
2, work efficiency is high, and preventive effect is outstanding.Use this hot mist machine dispenser, can increase substantially efficient, improve work efficiency several times to tens times, reduce agricultural cost.Secondly, this thermal fog is a main active with the pyraclostrobin, and the speed of knocking down is fast, and preventive effect is outstanding, safety and environmental protection.
3, simple to operate, labour intensity is little, and cost is low.
