Description
Technical field
This invention relates to a kind of composition pesticide and uses thereof.This composition pesticide is to be active ingredient with spiral shell mite ester and capillary, is used to prevent and treat the mite pest on the agricultural, especially is suitable for preventing and treating Panonychus citri and Tetranychus urticae.
Background technology
Spiral shell mite ester has another name called spirodiclofen, English general Spirodiclofen by name.It belongs to novel tetronic acid class miticide.By suppressing the lipogenesis in the evil mite body, destroy the energy metabolism activity of acarid.It is distinguished to mite ovum effect, if mite also has good contact toxicity, though to the female one-tenth mite poor effect of tagging, female one-tenth mite touches the ovum that is produced behind the medicine has exhausted major part not hatch, and dies from late embryogenesis to the children.It is a kind of efficient non-internal-absorting leaf surface treatment miticide, does not have the cross resistance problem with other existing miticide, shows good preventive effect and outstanding lasting effect, is particularly suitable for preventing and treating the pest mite class that existing miticide is produced resistance.
Capillary, English general Chlorfenapyr by name.It is a kind of new pyrrole insecticides.Mechanism of action uniqueness is mainly used in the control agricultural and goes up important insect such as beet armyworm, prodenia litura, and diamond-back moth, cabbage caterpillar etc. also have good control efficiency to harmful mite common on the agricultural such as Tetranychus urticae, Tetranychus cinnabarinus etc.There is not cross resistance with conventional pesticide.
The above-mentioned mite class of mentioning has another name called two spotted spider mite, white spider etc., belongs to the Arthropoda arachnids.The mite class of crop of mainly causing harm on agricultural mainly contains Panonychus citri, Tetranychus cinnabarinus, Tetranychus urticae, goitre mite and rust mite.The mite class of these crops of causing harm has usually that egg laying amount is big, and reproduction speed is fast, and population density is big, and generation overlap is obvious, and characteristics such as easily develop immunity to drugs.Usually cause fruit to spend skin, the leaf chlorosis, fruit tree nutrition is bad, occurs falling flower at last, falls leaf, falls destructive consequence such as fruit.
In the real process of China's agricultural production, chemical control is the main effective means of control mite class.The problem that the chemical control insect is easy to generate most is the generation of pest resistance to insecticide.The mite class easily develops immunity to drugs, panonychus citri especially, and under the environmental condition of long-term prescription, resistance increases obviously.Medicaments such as main control mite class medicament such as pyridaben, azacyclotin, Hexythiazox, four mite piperazines use the harm of uncontrollable mite class separately.
Go up the mite pest that produces resistance for control agricultural, a kind of way is to release the new component that new and existing kind do not have cross resistance.But, the development cost height of new active ingredient, the construction cycle is long, and all produces the speed of resistance forever less than insect.Other method such as crop allocation adjustment, biological control etc. in the process of practical operation, are difficult to really play obvious effects.
In China, because spiral shell mite ester needs import, be difficult to obtain, and cost an arm and a leg, its preparation of making uses and is confined to partly developed area, can not be used by all have the peasant in the area that needs.Because resistance problem, other cheap miticide effect commonly used is poor again.Therefore, control efficiency is good, and the relatively low miticide of use cost is the demand that vast farmers is thirsted for most.
Summary of the invention
For a kind of efficient miticide of preventing and treating evil mites such as Panonychus citri that agricultural go up to produce resistance, Tetranychus urticae is provided, we have carried out mutual composite research with compositions such as spiral shell mite ester, capillaries.
