Description
Technical field
The present invention relates to pesticide new product and technical field of pesticide combination, more particularly to a kind of chloropyridine derivative containing 2-
Pesticidal combination.
Background technology
The agricultural chemicals of commercial type causes the insect of crops to develop immunity to drugs, agriculture due to use for a long time, heavy dose of
Medicine prevention effect is poor, usage amount is big, the desinsection duration is short, the problems such as also cause soil pollution, nutrition leak, have impact on farming
The harvest of thing, causes the underproduction of Planting household, so a kind of new insecticide of research and development is imperative to change the status quo.Now
Different agriculture the effective elements of the medicines compounding is made agricultural chemicals, is exploitation at present and development novel pesticide and preventing and treating agriculturally resistance germ
One kind effectively and quick way.After the pestsides synthesis of different cultivars, three kinds of type of action are typically exhibited：Summation action,
Synergistic effect and antagonism.But which kind of effect be specially, it is impossible to predict, only just be can know that by lot of experiments.Compounding increases
Effect is formulated well, can significantly improve actual prevention effect, reduces the usage amount of agricultural chemicals, extends desinsection duration of efficacy,
It is the important means of integrated control disease so as to greatly delay the generation speed of pest resistance to insecticide.The present invention passes through a large amount of rooms
Interior research and field experiment, have filtered out the complex composition containing 2- chloropyridine derivatives, and mutually compounding has within the specific limits

Road.
Nereistoxin insecticides, have to insect it is very strong tag and fumigation action, some kinds also have Antifeedant Effects.
There is lethality to adult, larva, ovum, existing quick-acting has lasting effect more long again, thus when field uses, the optimum period for applying fertilizer
It is long, prevention effect stabilization.The multiple leafeating insects that can be used to prevent and treat in paddy rice, vegetables, sugarcane, fruit tree, the various crop such as tea tree,
Borer pest, some kinds also have good prevention effect to aphid, leafhopper, plant hopper, thrips mite class etc..
Dimehypo is nereistoxin insecticides, is a kind of never poison, there is very strong systemic action, can by the leaf of crop,
Root etc. absorbs and conducts, to for crops such as sugarcane, corn, paddy rice, peanuts, preventing and treating the insects such as snout moth's larva, subterranean pest-insect.
Cupric sulfate is sandworm toxin insecticide, with stomach toxicity, is tagged and Uptake and translocation effect, also there is certain stifling work
With energy effectively preventing snout moth's larva.
Cartap, is the bio-imitability agricultural chemicals for simulating nereistoxin synthesis, a kind of sandworm toxin insecticide.Kill snout moth's larva
Red stomach poison function is strong, while have tagging and certain food refusal, ovicidal etc. are acted on.Snout moth's larva, subterranean pest-insect to crops etc. are knocked down
Hurry up, the longevity of residure is long, desinsection wide spectrum.
