The invention potato seed coating agent relates to the pesticide field, the aphids and late blight are commonly occurred in the potato production, they are the most serious pest and disease, in recent years the new control method is seed dressing with chemicals, but the method has the disadvantages of high dropping rate and short effective period, the invention provides a water-based suspended potato special seed coating agent produced with a suspending agent processing technique, the raw material contains pesticide effective ingredients metalaxyl, imidacloprid and many kinds of accessories: growth regulator, dispersant, anticaking agent, suspending agent, filmerformer, fillings, preservative and colorant, the invention has efficient, sustained-release role in growing period, and has beneficial effects of long-term efficiency, low toxicity, pollution-free, environmental protection, labor and time saving, and low production cost.
Description
Technical field
The present invention relates to pesticide field, especially potato is used agricultural chemicals.
Background technology
Aphid and late blight are that the most general, the most serious damage by disease and insect that causes damage take place during potato produces, and usually mix and endanger.Aphid not only can be stung suction juice, causes the plant local necrosis, and even more serious is can be by getting the food viral disease that spreads disease, and causes that kind degenerates fast, and at present under the background of no effective anti-aphid kind, its control mainly is to spray the chemical agent optimum period and utilize natural enemy; Late disease bacteria is a kind of plant pathogenic fungi, and the potato seed of carrying disease germs is considered to disease spread and popular important step at present.Planting the clothing agent is a kind of formulations of pesticide that combined by agricultural chemicals, little fertilizer, film forming agent, filler, relevant auxiliary agent, it is a kind of new seed processing technology, on crops such as wheat, corn, cotton, beet, sunflower, plant seeds by airplane herbage, be used widely, remarkable to agricultural insect such as control soil insect, aphid, thrips, leafhopper and soil-borne disease effect, and the time and labour saving, to compare pollution relative little with other pesticide application technology.The research of handling for seed potato is both at home and abroad at present reported few, method commonly used in the production is except the ash seed dressing of routine, utilize gradient magnetic to handle potato seed in addition, " 911 " root-inducing powder, " AF liquid " soak methods such as potato seed, and its purpose mainly is to play the effect of regulation and control growth.Utilize the chemical agent seed dressing that report is arranged in recent years, as utilize the metalaxyl manganese-zinc wettable powder seed dressing to prevent and treat late blight, virus of A seed dressing control potato virus disease, imidacloprid wettable powder seed dressing control seed potato aphid in seedling stage.Relatively short shortcoming of ubiquity expulsion rate height, lasting period behind the above-mentioned dressing seed.The seed-dressing agent special of relevant potato does not appear in the newspapers as yet.
Summary of the invention
The purpose of this invention is to provide a kind of potato seed-coating agent and preparation method thereof.According to the occurrence characteristic of controlling object, selecting higher effective and lower toxic pesticide targetedly is active component, and a kind of water base property suspension potato seed-dressing agent special that adopts corresponding suspending agent processing technology to be prepared from is used for the control of potato aphid in seedling stage and late blight.
The technical scheme that realizes the foregoing invention purpose is as follows:
Potato seed-coating agent has acceptable auxiliary on pesticide active ingredient and the Pesticide Science, and the weight percent proportioning of each raw material is as follows:
Pesticide activity component metalaxyl 5-15%
Imidacloprid 1-2.5%
Growth regulator 0.10.5%
Dispersant 2-7%
Anticaking agent 1-4%
Suspending agent 1-6%
Film forming agent 0.1-3%
Filler 1-10%
Preservative 1-3%
Colouring agent 0.5-5%
Water surplus
Growth regulator is gibberellin or No. 5 root-inducing powders of ABT or fulvic acid or oil growth regulator or above-mentioned multiple material composition.
Dispersant is polyoxyethylene nonylphenol ether or OPEO or phenethyl phenol polyethenoxy ether or fatty alcohol-polyoxyethylene ether or polyoxyethylene alkylphenol ether, or above-mentioned multiple material is formed.
Anticaking agent is sodium silicoaluminate or tricalcium phosphate or silica or above-mentioned multiple material composition.
Suspending agent is xanthans or white carbon or polyvinyl alcohol or sodium carboxymethylcellulose or the polyethylene pyrrole irons alkane ketone or above-mentioned multiple material is formed.
Film forming agent is polyvinyl alcohol or polyvinyl acetate or modified starch or above-mentioned multiple material composition.
Filler is kaolin or bentonite or concavo-convex rod ore deposit clay or diatomite or talcum powder or above-mentioned multiple material composition.
Preservative is formaldehyde or Sodium Benzoate or potassium sorbate.
Colouring agent is that warning colouration is acid scarlet or Acid Red B.
The potato seed-coating agent preparation method is as follows:
A, in the high-shear emulsifying dispersion machine, add the former medicine of metalaxyl, the former medicine of Imidacloprid, growth regulator, dispersant, anticaking agent, film forming agent, filler, preservative, the colouring agent of metering and the water of supplying by proportioning, mix.
B, above-mentioned mixed liquor was disperseed about 30 minutes at homogeneous under the vacuum tightness condition.
C, the at the uniform velocity even amount of above-mentioned mixed liquor is added in the sand mill that has circulating water cooling device ground about 1 hour again, add the aqueous solution that suspending agent is made into and regulate viscosity, discharging after the mixing and stirring.
D, weigh, pack.
As the metalaxyl of bactericide, molecular formula is: C in the prescription

2, nicotinoids super-high-efficient systemic insecticide is the acting body of nicotinic acid acetylcholinesterase acceptor, it is malfunctioning to disturb the pest movements nervous system that chemical signal is transmitted.To characteristics such as people, animal, plant and natural enemies securities, and in soil and water body, do not move, can leaching infiltration not go in the deep soil.Be mainly used in controlling sucking insects and resistant strain thereof, as aphid, leafhopper, aleyrodid, plant hopper, thrips etc.Insecticides adjuvants, film forming agent, auxiliary material, water etc. in the former medicine of these two kinds of agricultural chemicals and the prescription are through mixing, high cut disperse emulsification, circulation sand milling, obtaining finished product after regulating viscosity, packing.
The present invention is a kind of suspension liquid of being made through technologies such as mixing, dispersion, sand millings by plurality of raw materials of magneta colour; Before potato sowing with the present invention according to 1: 100 pesticide-seeds ratio dressing of seed potato after, naturally can form the medicine film on the seed potato surface after drying, by the systemic action of medicine and the conduction of plant, during plant growth, can be continual each tissue of arrival crop, thereby play promote to grow, the effect of preventing disease pest control.
Use through indoor test and field and to show can emerge ahead of time and improve and the vaccine rate, obvious to early stage late blight of potato and aphid control action, can obviously alleviate sick breaking out of evil early of later stage with popular.
The present invention has following beneficial effect:
1, efficient, slowly-releasing, long-term effectively medium-term and long-term at potato raw;
2, low toxicity is nuisanceless, helps environmental protection;
3, use and to save time, the saving of labor, to reduce production costs.
