Description
Technical field
The present invention relates to a kind of seed treatment based on insect viruses and Diacloden.
Background technology
Seed coat agent, seed dressing and seed soaking agent are referred to as seed treatment.Seed coat agent refers to outside the plant seed of dry and moisture state, with composition parcels such as the agricultural chemicals containing adhesive or fertilizer, makes it to be formed the protective layer having certain function and wrap up intensity.This process is referred to as seed pelleting, and is referred to as seed coat agent wrapping in seed exogenesis composition.If medicament only forms unstable adsorption layer at outer covering of the seed, be called dressing seed agent.Powder seed dressing is wherein called again the agent of seed meal clothing.That soaks seed with liquid preparation is called seed soaking agent.The active component of seed treatment, be generally insecticide, bactericide, rodenticide, plant growth regulator, fertilizer, rare earth element, biologic product etc., its main effect wraps up seed by active matter, to eliminate insect pest, disease and to provide seed nutritional, promotes seed growth effect.Seed treatment has efficient action character.When seed sprouting, multiple germ propagates the radical bud of infecting tender seedling by the mode of seed, soil, cause plant disease; Meanwhile, a lot of soil insect, nematode, midge worm, muroid are stung and are chewed seed and seedling, cause seed not emerge, or death of seedling.Seed treatment, by wrapping up one deck active parasite killing, sterilization around seed, killing the composition of mouse, effectively can avoid germ, the infringement of insect and muroid.On the other hand, due to when seed sprouting be usually also insect survive the winter recovery time, the insect individuality in this time is the most small and weak, and the effective insecticidal constituent also the most easily contained by seed coat agent kills, and thus in seed treatment, the effect of active ingredient is best at this moment.
Seed treatment has economic feature, because seed treatment is close to seed, forms protective barrier, makes the pest of surrounding be difficult to existence.Medicine scatters around seed, and the efficacy of a drug is concentrated, and availability is high.The methods such as specific leaf area sprinkling, soil treatment, pesticide-clay mixture, poison bait, economize medicine, saving of labor, save time.Seed treatment has safe feature, and the among a small circle use of seed treatment around seed, does not pollute atmospheric environment, soil.The use of seed treatment makes crop field upper part residual quantity greatly reduce.Seed treatment has the long feature of lasting effect.After seed treatment parcel seed, medicine generally can not soil diffusion towards periphery rapidly, but slowly to spread, is not exposed to the sun and rain and temperatures involved, so action time is longer.
Diacloden is a kind of insecticidal spectrum insecticide very widely, belongs to second generation nicotinic insecticide, has unique chemistry and biochemical characteristic.Diacloden is different from other insecticides completely to the action site of insect, therefore there is not cross resistance; Diacloden is a kind of micromolecular compound, has desirable Determination of oil-water partition coefficient and water-soluble, can be uniformly distributed, very easily absorbed by root system of plant and conduct in plant corpus under the condition that therefore no matter Diacloden irrigates in arid or high strength in soil.Diacloden effect crop is corn, wheat, cotton, peanut, soybean, rape, vegetables, melon and fruit, potato etc.The Major Pests of Diacloden control of maize have corn leaf aphids, corn leafhopper, small brown rice planthopper (MRDV), wireworm, grub, maggot, corn flea beetle.Diacloden is the seed treatment insecticides of globalization famous brand.Although Diacloden has above-mentioned advantage, it has poor biocompatibility as chemical pesticide, and lasting effect is short, and unstable to alkaline environment especially, the most microorganisms in soil can carry out degrading etc. shortcoming to it.
Summary of the invention
