Description
TECHNICAL FIELD
The invention relates to the field of pesticides, in particular to a kind of potato seed coating agent.
BACKGROUND
Aphids and late blight are the most prevalent in potato production, resulting in most serious diseases and pests loss, often being compromised. The aphids can not only puncture the juice, cause partial necrosis of the plant, but also can cause rapid degradation of the variety by taking food to propagate the virus disease; the prevention and treatment of the aphids is mainly in the context of an effective aphid resistance variety; the prevention and treatment of the aphids is mainly a chemical agent aptamer spray and the natural enemy; the late blight bacteria is a plant pathogenic fungus, and the strain potatoes are currently considered to be an important link of disease propagation and prevalence.
The seed coating agent is a pesticide dosage form which is formed by combining a pesticide, a micro-fertilizer, a film-forming agent, a filler and a related auxiliary agent, is a new seed treatment technology and widely applied to crops such as wheat, corn, cotton, beet, sunflower, flying forage grass and the like, and has a remarkable effect on preventing and treating agricultural insects such as underground pests, aphids, thistle, leaf cicada and the like. It saves time and labor, and results in less pollution compared with other pesticide application technologies. At present, there are not many research reports on the treatment of potato seed potatoes at home and abroad. In addition to the conventional seed dressing methods, there are also methods for treating seed potatoes with gradient magnetic fields, 911 rooting powder, and AF liquid soaking seed potatoes for regulating and controlling the growth. Chemical pharmacy seed dressing has been reported in recent years, such as
2020100515 03 Apr 2020 using Use metalaxyl manganese zinc wettable powder for seed dressing to prevent late blight, virus A dressing for potato virus disease, and imidacloprid wettable powder for dressing for control of aphids in potato seedlings at seedling stage. These methods have the defects such as high shedding rate and relatively short lasting period after seed dressing. Special seed coatings agent for potatoes have not been reported.
SUMMARY OF THE INVENTION
The invention discloses a potato seed coating agent and a preparation method thereof. According to the occurrence characteristics of the prevention and treatment object, the high-efficiency low-toxicity pesticide is selected in a targeted manner as an active ingredient, and the special seed coating agent for water-based suspended potatoes prepared by using the corresponding suspending agent processing technology is used for preventing and treating aphids and late blight of the potato seedling stage.
The technical solution for achieving the purpose of the invention is as follows:
Potato seed coating agent is provided with a pesticide effective component and a pesticide acceptable auxiliary material, wherein the weight percentage ratio of each ingredient is as follows: pesticide active component metalaxyl 5-15% imidacloprid 1-2.5% growth regulator 0.10. 5% dispersing agent 2-7% anti-Caking Agent 1-4% suspending Agent 1-6% film-forming agent 0.1-3% filler 1-10%
2020100515 03 Apr 2020 preservative 1-3% colorant 0.5-5% water Balance?
the growth regulator is gibberellin or ABT 5 rooting powder or fulvic acid or a petroleum growth promoter or a plurality of substances the dispersant is nonylphenol polyoxyethylene ether or octylphenol polyoxyethylene ether or phenethylphenol polyoxyethylene ether or fatty alcohol polyoxyethylene ether or alkylphenol polyoxyethylene ether, or a combination thereof, the anti-caking agent is sodium aluminosilicate or tricalcium phosphate or silicon dioxide or a combination thereof, the suspending agent is xanthan gum or white carbon black or polyvinyl alcohol or carboxymethyl cellulose sodium or polyvinylpyrrolidone or a combination thereof, the film-forming agent is polyvinyl alcohol or vinyl polyester acid vinyl ester or modified starch or a combination thereof, the filler is kaolin or bentonite or attapulgite clay or diatomite or talcum powder or a plurality of substances the preservative is formaldehyde or sodium benzoate or potassium sorbate.
The colorant as alert color is an acidic red or acidic red B.
The potato seed coating agent is prepared by following method comprising steps:
A. adding metered metalaxyl raw drugs, imidacloprid raw drugs, growth regulators, dispersing agents, anti-caking agents, film-forming agents, fillers, preservatives, colorant and water in a highshear emulsifying dispersion machine in proportion, and stirring and mixing;
B. uniformly dispersing the above mixed liquid under a vacuum sealing condition for about 30 minutes;
2020100515 03 Apr 2020
C. adding the above mixed liquid into the sand mill with a circulating water cooling device at a uniform speed to grind for about 1 hour, add an aqueous solution prepared by a suspending agent to adjust the viscosity, and mix and stir before discharging;
D. weigh and package.
Metalaxyl as a bactericide in the formula has the formula C15H21NO4, and the chemical name is N(2,6-dimethylphenyl)) Methyl-N-(2-methoxyacetyl)-DL-aminopropionic acid methyl ester, ISO Universal Name: Metalaxyl, which is a novel high-efficiency endogenous bactericide, can penetrate the cell membrane of an ovalic bacteria with small lipophilicity, plays a bactericidal role, and has the selective specificity for the frost mold and the phytophthora in the ovalis, therefore it has good prevention and treatment effects on the late blight of the potato, the grape downy mildew, the hop downy mildew, the beet blight, the rape white rust disease, the tobacco black shank disease and the like. The imidacloprid as an insecticide, chemical name: 1-(6-chloropyridin-6-pyridylmethyl)-N-nitrobenzimidazolidine-6ylamine, the molecular formula: C9H10CIN5O2, is a nicotine super-efficient endogenous insecticide, which is an action body of acetylcholine acetylcholinesterase receptor for interfering with the pest's motor nervous system to disable chemical signal transmission. It is safe for people, livestock, plants, natural enemies and the like, does not move in soil and water, and does not spray into deep soil and Mainly used for preventing and treating puncture-type pests and resistant strains thereof, such as aphids, leaf cicadae, bemisia tabaci, fly lice, thistle and the like. The two pesticides are mixed with a pesticide auxiliary agent, a film-forming agent, an auxiliary material, water and the like in the formula, high-shear dispersion emulsification, cyclic sanding, viscosity adjustment and sub packaging are carried out to obtain a finished product.
The invention is a reddish-colored suspension liquid made of a variety of ingredients through processes such as mixing, dispersing and sanding. Before the seed potato is sowed, coated by invention coating agent according to the 1: 100 ratio of coating agent and potato, then naturally dried, a drug film can be formed on the surface of the seed potato. During the growth, it can continuously reach
2020100515 03 Apr 2020 the various tissues of the crop, thereby playing a role in promoting growth, preventing diseases and controlling insects.
The lab test and field application show that an early emergence and increased germination rate are observed. The effect on late blight and aphids of the potatoes is obvious, and the outbreak and the popularity of early stage diseases can be obviously reduced.
The invention has the following beneficial effects:
1. The method is efficient, slow-release and long-term effective in the growth period of the potatoes;
2. low-toxicity and pollution-free, and is beneficial to environmental protection;
3. Time and labor are saved, and the production cost is reduced.
