Abstract

The invention discloses a mixed insecticide of tea saponin and an acaricide. The mixed pesticide preparation comprises the components in percent by weight: 0.01% to 80% of tea saponin, 0.5% to 80% of acaricide 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 acaricide 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 control process 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

The insecticide that Tea Saponin and miticide are mixed
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 miticide are mixed.
Background technology
From the miticide of current use,, also be prone to decompose though great majority are compounds efficient, low toxicity; But the great majority in them all are never poisons; Mammiferous toxicity can not be ignored, environment is also had certain influence, harmful simultaneously mite is prone to produce resistance.Because acaricidal long-term, a large amount of unreasonable use of chemistry, and because the intrinsic shortcoming of some medicament itself has caused harmful mite to develop immunity to drugs.In the long run, acaricidal development is just towards the development of non-killing livestock property (insect hormone) noval chemical compound and biotype compound, to solve them to the toxicity of animal, drug-fast problem is taken place for pollution, the evil mite of environment.And use the miticide cost higher separately.
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 the most noticeable one type.Being mixed of the exploitation of botanical pesticide, botanical pesticide and chemical pesticide, botanical pesticide and being mixed of botanical pesticide all are the forward position and the focus of pesticide research in the world.
Tea Saponin (Tea saponin) is the vegetable insecticide that from the tea cake after the seed of plant of theaceae such as tea seed cake, the tea-seed oil expression, extracts, and belongs to pentacyclic triterpenoid, and its pure article 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.
But do not see the technology report about Tea Saponin and miticide combination operation technique scheme at present.
Summary of the invention
