Abstract
The invention discloses a mixed insecticide of tea saponin and a carbamate insecticide. The mixed pesticide preparation comprises the components in percent by weight: 0.01% to 80% of tea saponin, 0.5% to 80% of carbamate insecticide and the balance of assistant agent. The mixed pesticide preparation can be prepared into missible oil, wettable powder, microemulsion, a suspension agent, a suspension emulsion or a water emulsion. The carbamate insecticide and the tea saponin are selected for mixing, therefore, the mixed insecticide has obvious synergy; compared with a single agent, insecticidal activity is obviously enhanced; and the mixed insecticide has multiple treating effects on various pests, thereby reducing manpower and material utilization in the processes of controlling the pests and enhancing production benefits. At the same time, on the premise of ensuring medical effects, the invention remarkably reduces the cost. The mixed insecticide has various preparations, simple preparation method and high popularization value.
Description
Technical field
The present invention relates to a kind of agricultural insecticide, be specifically related to the insecticide that a kind of Tea Saponin and carbamate insecticide are mixed.
Background technology
Because long-term, a large amount of unreasonable uses of chemical pesticide, and because the intrinsic shortcoming of some medicament itself has caused insect generation " 3R " problem.Therefore, be object with the natural products, seek bioactivator, the research and development novel biopesticide enjoys attention at home and abroad, and wherein, botanical pesticide is a most noticeable class.Being mixed of the exploitation of botanical pesticide, botanical pesticide and chemical pesticide, botanical pesticide and being mixed of microbial pesticide all are the forward position and the focus of pesticide research in the world.
Tea Saponin (Tea saponin) is the vegetable insecticide that extracts from the tea cake after the seed of plant of theaceae such as tea seed cake, the tea-seed oil expression, belongs to pentacyclic triterpenoid, and its pure product are colorless prismatic crystal, have hygroscopicity, and bitter is pungent, and molecular formula is C
57H
90O
26, molecular weight is 1191.31,223～224 ℃ of fusing points, and soluble in water and organic solvents such as alcohols, organic acid are insoluble to organic solvents such as ether, benzinum, benzene.
Tea Saponin is a kind of nonionic surface active agent, has that stronger exhibition is puted forth effort, emulsifying ability, dispersion force, wetting power and a foaming power, and cold-blooded animal is had high poison, and people and animals are waited the nontoxic or low toxicity of homoiothermy animal.This compound has desinsection, sterilization, kills mite and reduces capillary multiple function, has different mechanism of action with chemical pesticide.But Tea Saponin has action of contace poison and stomach poison function to damage by disease and insect, but Tea Saponin quick-acting is poor, application dosage is big, and result of use is bad separately.
The most kinds of carbamate insecticide are quick-acting, and the longevity of residure is short, and selectivity is strong.Good to leafhopper, plant hopper, thrips, corn borer preventive effect, to natural enemies security.Most kinds are easily degraded in biological and environment to the higher plant low toxicity.But the independent use of carbamate insecticide is very easily developed immunity to drugs.
But be used in combination technical scheme about Tea Saponin and carbamate insecticide at present and do not see the technology report.
Summary of the invention
