Abstract
The invention discloses an insecticidal composition containing dicyclanil and nereistoxin. The composition contains an active component A and an active component B, wherein the active component A is selected from dicyclanil, the active component B is selected from anyone of thiocyclam, dimehypo and monosultap, and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition has a synergistic effect on a plurality of pests harming the agricultural production, reduces the pesticide dose, reduces the residual quantity of pesticides on crops, reduces the environmental pollution, is safe to humans and animals, has a good environmental compatibility, and realizes the difficult generation of the drug resistance of the pests.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of Pesticidal combination on crop pests containing CGA 183893 and neires toxin.
Background technology
CGA 183893 (dicyclanil) chemical name: 4,6-diaminourea-2-cyclopropylamino pyrimidine-5-nitrile, molecular formula: C
8H
10N
6.The decortication of CGA 183893 interference insect, after being absorbed by the insect genital system, stop larvae pupation or become worm.
Thiocyclam (thiocyclam-hydrogenoxalate) chemical name: N, N-dimethyl 1,2,3-trithio chlorodioxin-5-amido oxalate, molecular formula: C
7H
13NO
4S
3, thiocyclam is sandworm toxin insecticide, has and tags and stomach poison function, and certain interior suction and fumigation action are also arranged, and can ovicidal.Toxic effect to insect is slower, and poisoning the lighter can be brought back to life sometimes.It disappears comparatively fast in plant corpus, and the longevity of residure is shorter, and residual quantity during results in crop seldom.Thiocyclam is effective to Lepidoptera, coleoptera, homoptera pest, can be used for preventing and treating the various pests on paddy rice, corn, beet, fruit tree, vegetables, but large to the toxicity of silkworm.
Dimehypo (bisultap) chemical name: 2-N, N dimethylamine base-1, two (the thiosulfonic acid sodium base) propane of 3-, molecular formula: C
5H
11NO
6S
4Na
2, dimehypo is a kind of never poison, have tag, stomach kills and fumigation action, insect contact and take food medicament after show that blunt, slow in action, as to lose infringement crop ability, stasi, polypide are softening, paralysis is until dead; Dimehypo has very strong systemic action, can be absorbed and conduction by the leaf of crop, root etc.
Desinsection list (monosultap) chemical name: 2-N, N dimethylamine base-1-sodium thiosulfate base-3-propane thiosulfate, molecular formula: C
5H
14O
7S
4Na, the desinsection list is a kind of manually analog of synthetic nereistoxin, enters in insect bodies and is converted into rapidly clam worm element or Dihydronereistoxin element.This medicine is the acetylcholine competitive inhibitor, have stronger tag, stomach toxicity and interior suction conduction, the larva of lepidoptera pest is had to preventive and therapeutic effect preferably, this medicine is mainly used in preventing and treating the insect on the crops such as sugarcane, paddy rice.
Yet, in the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.The different cultivars composition carries out composite, is the very common method of control resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor research, find after CGA 183893 and thiocyclam, dimehypo, desinsection list is composite to produce good synergistic effect, and composite relevant report is not yet open about CGA 183893 and thiocyclam, dimehypo, desinsection list.
Summary of the invention
The objective of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect the is good Pesticidal combination containing CGA 183893 and neires toxin.
The Pesticidal combination containing CGA 183893 and neires toxin that the present invention proposes contains active components A and active component B, active components A and active component B weight ratio are 1 ︰ 80 ~ 60 ︰ 1, described active components A is selected from CGA 183893, active component B is selected from a kind of in thiocyclam, dimehypo, desinsection list, and active components A and the preferred weight ratio of active component B are 1 ︰ 60 ~ 30 ︰ 1; More preferably the weight ratio of CGA 183893 and thiocyclam is 1 ︰ 30 ~ 3 ︰ 1, and the weight ratio of CGA 183893 and dimehypo is 1 ︰ 30 ~ 2 ︰ 1, and the weight ratio of CGA 183893 and desinsection list is 1 ︰ 30 ~ 3 ︰ 1.
The purposes of the described Pesticidal combination containing CGA 183893 and neires toxin for preventing and treating insect on fruit tree, vegetables, cereal crops, fiber crop, ornamental plants.
