The novel suspension seed coating agent disclosed by the invention is not only good in pharmacological effect, long in lasting effect, high in effect, economic and safe but also is capable of reducing environmental pollution, increasing the utilization rate of pesticides and reducing the use amount of the pesticides. The novel suspension seed coating agent is worthy of being popularized and used.
Description
Technical field
The present invention relates to insecticide, the wide field of insecticidal spectrum, specifically, relate to a kind of Novel suspending seed coat agent.
Background technology
Homoptera is wherein 1 order of Arthropoda (Arthropoda), Mandibulata (Mandibulata), Insecta (Insecta), Pterigota (Pterygota), there is sucking mouth parts, front and rear wing film quality is transparent, shape, quality are identical, two pairs of wings, time static is that ridge puts back, the large class insect that fore wing quality is homogeneous more.In China, the insect of Homoptera mainly comprises cicada, froghopper, leafhopper, horned frog, plant hopper, plant hopper, wood louse, aleyrodid, aphid and coccid.
Homoptera insect is all food with water, and wherein numerous species can propagate the viroses of plant, is important pest.At present, China's agriculture field is to the control of this class pest mainly to spray Diacloden, and namely the mu Diacloden water dispersible granules 3.2-4.8 gram of 25%, is watered 50-60 kilogram of even spraying.But this prevention and controls effect is more and more not obvious, and crops create larger dependence to agrochemical agricultural chemicals, result in indiscriminate use of pesticide, not only make crop production reduction, also add cost accounting, and causes certain environmental pollution.So, research and develop novel wide-spectrum bactericide, insecticide is the task of top priority.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned defect, provides the Novel suspending seed coat agent that a kind of low toxicity, wide spectrum, control efficiency are good.
For solving the problem, the technical solution adopted in the present invention is:
A kind of Novel suspending seed coat agent, is characterized in that: described seed coat agent is by Diacloden, ethiprole and pyraclostrobin, and the percentage by weight that each composition accounts for seed coat agent is as follows:
Diacloden 5% ~ 30%
Ethiprole 5% ~ 30%
Pyraclostrobin 0.5% ~ 20%.
Improve as one:
The percentage by weight that each composition accounts for seed coat agent is as follows:
Diacloden 5%
Ethiprole 5%
Pyraclostrobin 5%.
As further improvement:
The percentage by weight that each composition accounts for seed coat agent is as follows:
Diacloden 10%
Ethiprole 10%
Pyraclostrobin 8%.
As further improving:
The percentage by weight that each composition accounts for seed coat agent is as follows:
Diacloden 20%
Ethiprole 20%
Pyraclostrobin 10%.
As further improving:
The percentage by weight that each composition accounts for seed coat agent is as follows:
Diacloden 30%
Ethiprole 30%
Pyraclostrobin 10%.
Wherein, Diacloden is second generation nicotinic insecticide, acts on insect acetylcholinesterases acceptor, has special efficacy to sucking pest, have tag, stomach toxicity and systemic action, instant effect, lasting period are long.
Ethiprole is that a kind of Phenylpyrazole insecticides, insecticidal spectrum are wide, to insect based on stomach poison function, have concurrently and tag and certain systemic action, its mechanism of action is the chloride metabolism hindering insect γ-aminobutyric acid to control, therefore very high insecticidal activity is had, to crop without poisoning to important pests such as aphid, leafhopper, plant hopper, lepidopterous larvae, fly class and coleopteras.This medicament can impose on soil, also can foliar spray.
Pyraclostrobin is New-type wide-spectrum bactericide.Mitochondrial respiratory inhibitor.There is protection, treatment, blade infiltration conduction.
Seed coat agent generally also comprises seed coat agent auxiliary agent, and general has:
Dispersant: screen multiple dispersant, chooses the emulsifying dispersant wherein showing dispersiveness and coating uniformity preferably.The dispersant be suitable for can be the polymer of the polymer of polyvinyl acetate and polyvinyl alcohol, ethyl acrylate and vinyl acetate.
Film forming agent: film forming agent allows seed coat agent have good film forming and plants the key assistant of clothing fastness, chooses the film forming agent showing good viscosity and heat storage, cold storage.Polyvinyl acetate and the polyvinyl resin of the film forming agent be suitable for can be weight ratio be 6:4.
Antifreezing agent: for prevention seed coat agent freezes or crystallization in storage, transportation, impact uses, and spy have selected three kinds of antifreezing agents and tests.Result shows, adopts ethylene glycol, glycerine effect better, in conjunction with the factor such as price and use, selects ethylene glycol as antifreezing agent.
The screening of other auxiliary agents: choose applicable bleeding agent, emulsified wetting suspending agent, diffusant, viscosity stabiliser, defoamer, warning colouration, PH align agent, adhesive etc.
Owing to have employed technique scheme, the present invention has the following advantages:
1, good drug efficacy, the former medicine average grain diameter of the dispersed solid of suspension seed-coating agent is 0.1-7.0 micron, and particle is close to spherical, and particle size range is little, is evenly distributed; Simultaneously because the micro-bubble formed in process of lapping is adsorbed in particle surface, thus suspensibility and stability are improved; Dress seed or strong adhesion after foliage spray, rate of film build is high, has ensured the germination rate of seed.
2, production and application safety, cost is low, and environmental pollution is few, this seed coat agent is generally with water level continuous print dispersion, uses sand mill wet production, so both can save a large amount of organic solvent, reduce costs, the stimulation of organic solvent to operator and the pollution of environment can be reduced again.Do not produce in production " three wastes ", without pulvis and wettable dust from flying, produce, accumulating is all safer.
Embodiment
For understanding the present invention further,
Below in conjunction with embodiment, the present invention will be further described.According to the present invention, according to controlling object, a situation arises determines the consumption that is suitable for, and unobstructed formulation rate is the weight ratio of seed coat agent and seed is 1:30 ~ 60.
