Description
Technical field
The invention belongs to technical field of pesticide, the active component that it is characterized in that relating to a kind of composition pesticide of synergy, particularly said composition is nimbin on the one hand, is Tea Saponin on the other hand.
Background technology
Nimbin (Azadirachtin) can reduce insect haemocyte quantity, reduce protein content in the hemolymph, reduce trehalose and metal cation concentration in the hemolymph; The activity that can suppress protease, amylase, lipase, phosphatase and glucolase in insect midgut esterase and the fat-body; Reduce the food rate of getting of insect and to the trans-utilization rate of food; Can influence the normal respiratory rhythm of insect, reduce DNA and rna content in the insect fat-body, reduce the content of protein, glycogen and lipid in female worm's ovum nest, oviduct, the spermatheca and the activity of some enzymes; Influential to the male worm genital system; Make the brain, corporal allata, corpora cardiaca, prothoracic gland, fat-body etc. of insect that pathology take place, influence insect bodies internal hormone balance, thereby interference insect grows.Nimbin is at present universally acknowledged wide spectrum, efficient, low toxicity, is prone to the insecticide of degraded, noresidue and does not have pesticide resistance; To 10 orders more than 400 kind of agricultural, storage and sanitary insect pest; Particularly Lepidoptera, coleopteran pest there are special efficacy, and people and animals and surrounding environment are not had any pollution.Yet the nimbin botanical pesticide also has the shortcoming of himself: one, compound structure is complicated, is difficult for synthetic; Two, there is region in the distribution of material plant, and the limiting factor that in the selection in processing place, receives is many; Three, raw-material collection has seasonality, and the source is restricted.
Therefore; In pesticidal preparations, use synergist rightly; Saving the usage amount of nimbin active ingredient to greatest extent, and do not influence drug effect and the low toxicity and the environmental safety of preparation simultaneously, is problem demanding prompt solution in the sustainable development of nimbin natural source agricultural chemicals.
Tea Saponin (Tea saponin; TS) have another name called tea saponin, tea saponin, tea saponarin; It is a kind of well behaved natural surfactant; Not only have good emulsifying, foaming, dispersion, infiltration, wetting isoreactivity effect, but also have anti-inflammatory, pain relieving, sterilization, pharmacological action such as antipruritic.Tea Saponin is the good auxiliary agent of aqua or soluble powder agricultural chemicals, plays the synergistic effect to agricultural chemicals.Tea Saponin can be degraded automatically, and it can not exert an influence to the chemical property of agricultural chemicals in decomposable process.Tea Saponin can be used as pesticide activity component and uses, but Tea Saponin quick-acting is poor, application dosage is big, and result of use is bad separately.
