Description
Technical field
The present invention relates to pesticide field, particularly, relate to the application of Pesticidal combination in soil insect such as control wireworm and grub etc. containing Diacloden and bromine cyanogen insect amide.
Background technology
Soil insect refers to that the most of the time in all one's life lives in soil, to cause harm the insect of the shy stem of plant underground roots, stem, seed or near-earth, have that kind is many, distribution is wide, host range is wide, life cycle is long, generation and soil and the feature such as vegetation is closely related, damage and yield loss is large.Many crops cause the disconnected ridge that is short of seedling, the large stretch of death of plant because of it, and even No kernels or seeds are gathered, as in a year of scarcity, has a strong impact on high yield and the high-quality of crops.Therefore, controlling causing harm of soil insect is the key link that agricultural production can not be ignored.
According to a large amount of investigation over nearly 20 years, China the greater part farmland underground insect, based on grub and wireworm, accounts for nearly 90% of soil insect total worm amount altogether.Because soil insect occurs hidden, the features such as Species differences is large, cause very large difficulty to its control, for controlling causing harm of this class pest, chemical pesticide is still important means of prevention.Thus, the screening of high-efficiency low-toxicity chemical pesticide and composite use thereof, compeled to save at eyebrow.
Diacloden (Thiamethoxam), chemical name is: 3-(2-chloro-1,3 thiazole-5-ylmethyl)-5-methyl isophthalic acid, 3,5-oxadiazines-4-base fork (nitro) amine, belongs to anabasine insecticide.Its mode of action be simulation acetylcholine, costimulatory receptor albumen, and the acetylcholine of this imitation can not degrade by acetylcholinesterase, insect is in fever always, until dead.Have good stomach toxicity and contact toxicity, strong Uptake and translocation, pests medicament, rapid suppression activity stops taking food, and dead gradually, and have the features such as efficient, the lasting period is long, its lasting period can reach about 1 month.But it separately, a large amount of use is easy produces obvious pesticide resistance.
Bromine cyanogen insect amide (Cyantraniliprole), chemical name is: the bromo-1-of 3-(3-chloro-2-pyridyl)-N-[4-cyano group-2-methyl-6-[(methylamino) carbonyl] phenyl]-1H-pyrazoles-5-formamide, it is the second generation ryanodine receptor inhibitor insecticides that success is developed after Rynaxypyr, bromine cyanogen insect amide is formed by the various polar groups changed on phenyl ring, have more efficient, applicable crops is more extensive, can effectively prevent and treat Lepidoptera, Semiptera and coleopteran pest etc.It carrys out pest control mainly through the ryanodine receptor activating target pest.The activation of ryanodine receptor can discharge the calcium ion of storage in striated muscle and smooth muscle cell, and result causes infringement muscular movement to regulate, benumb, and final insect is dead.This medicine shows the extremely significant selective difference of mammal and insect ryanodine receptor, substantially increases the safety to mammal, other vertebrates and other natural enemies.
Therefore, current researcher is devoted to study a kind of Pesticidal combination, can not only improve drug effect, reduce costs, and can avoid and delay pesticide resistance generation.And Diacloden and bromine cyanogen insect amide are cooperated the prior art of use all to concentrate on control insect on the ground, such as snout moth's larva, aphid, scale insect, leafhopper, brown planthopper, diamond-back moth, fly etc., its verification msg also only confirms to have good killing effect for above-mentioned ground insect.
Though the Diacloden of prior art report, for preventing and treating soil insect, does not have the purposes for wireworm and grub.Tool such as long-term, a large amount of are used alone this medicament, and the pesticide resistance of insect can rise very soon.The bromine cyanogen insect amide of prior art report does not have prevents and treats soil insect, the especially purposes of wireworm and grub specially.
Soil insect (undergroundinsect) refers to adult or in the history of life, certain one-phase lives in soil the insect endangering flowers and trees seed, seedling under ground portion or nearly table soil stem, their life habit, physiological structure characteristic and to the susceptibility of agricultural chemicals etc. all and on the ground insect have very big difference.Soil insect kind is a lot, mainly contain mole cricket, grub, wireworm, cutworm, root maggot, root stinkbug, root aphid, intend ground first, cricket, root a red-spotted lizard, root are chrysomelid, root longicorn, root weevil and termite etc.
Soil insect generally perches, breed and survive in soil, this proposes its control and compares higher requirement with ground insect, in general, mostly go up insect all to be killed by the mode of direct spraying pesticide, but for soil insect, because it is subject to the protection of soil, unless spray high concentration agricultural chemical (this situation is infeasible), in most cases, be difficult to effectively suppress soil insect.In North China of China, especially Hebei Province, endanger wireworm and grub most serious of all, very limited to their killing method at present.Therefore, need badly and find out the suitable insecticide that effectively can suppress soil insect especially wireworm and grub.
Prior art not yet finds medicament Diacloden and bromine cyanogen insect amide being joined together to use.The application of Diacloden and bromine cyanogen insect amide binary mixture preparation, reduces the Selective Pressure of each single dose to soil insect, contributes to delaying drug-fast generation.
Pesticidal combination containing Diacloden and bromine cyanogen insect amide of the present invention is being prevented and treated in soil insect wireworm and grub etc., has the following advantages:
1, Diacloden is different with the mechanism of action of bromine cyanogen insect amide to insect, and between the two composite has very high synergistic effect, is therefore a kind of desirable insecticide binary combination.
2, reach mutual supplement with each other's advantages, improve drug effect, reduce costs, the effect of delaying drug resistance, minimizing chemical pesticide consumption, reduce the residual quantity of agricultural chemicals on crop, alleviate environmental pollution; , insect good to person poultry safety, Environmental compatibility not easily develops immunity to drugs.
In a word, the Pesticidal combination containing Diacloden and bromine cyanogen insect amide that the present invention is to provide, combines the two and can give full play to respective advantage, can be used for preventing and treating soil insect; And the combination of two kinds of active ingredients has significant synergies, can reach and strengthen control efficiency and delay drug-fast effect, quick-acting and lasting effect are all better, are better than prior art.And can pesticide dosage be reduced, reduce costs, alleviate the pressure to environment.
