A kind of Pesticidal combination containing carbosulfan and chlorine fluorine cyanogen insect amide
Technical field
The invention belongs to pesticide field, and in particular to a kind of Insecticidal combinations containing carbosulfan and chlorine fluorine cyanogen insect amide
Thing.
Background technology
The resistance problem of agricultural pests is a global problem.As the continuity of Chemical Control of Harmful Insects, agricultural chemicals make
The increase of consumption and not scientifical use agricultural chemicals, pest resistance are increasingly serious, produce the pest species of resistance to be on the increase.Especially
It is the Lepidoptera class pest for causing harm to agricultural production serious, resistance level is higher, and resistance development speed is relatively fast.Meanwhile, it is high
The use agricultural chemicals of intensity, cause exceeded Practice for Pesticide Residue in Agricultural Products, environmental pollution and peasant's drug cost to increase etc., it is unfavorable for agricultural
Sustainable development.Therefore, efficient, low toxicity is researched and developed, the pesticide of environmental protection has actively meaning to agricultural sustainable development
Justice.
Carbosulfan (carbosulfan) belongs to carbamates, and its toxicity mechanism is to suppress insect acetylcholine
The activity of enzyme (Ache) and carboxy-lesterase, causes the accumulation of acetylcholine (Ach) and carboxylate, and the normal nerve of influence insect is passed
Lead and lethal.Carbosulfan lethality is strong, and instant effect is effective to adult and larva with stomach toxicity and action of contace poison, to making
Thing is harmless, the diversified economy crop pest such as the fruit such as oranges and tangerines and vegetables, corn, cotton, paddy rice, sugarcane can be prevented and treated, to aphid
Prevention effect is particularly excellent.
Chlorine fluorine cyanogen insect amide is the novel pesticide that Zhejiang Provincial Chemical Engineering Research Inst is voluntarily developed, code name ZJ4042, chemical name
Referred to as:The chloro- N of 3-1- (2- methyl -4- sevoflurane isopropyls base)-N2- (1- methyl isophthalic acids-cyano ethyl) neighbour's benzene two
Formamide, shown in structural formula following (I):
The insecticide belongs to new phthalic amide insecticides, is led to by activating blue Buddhist nun's alkali recipient cell Intracellular calcium release
Road, causes to store the runaway release of calcium ion, is few in number at present to act on insect cell orchid Buddhist nun's alkali (Ryanodine)
The compound of acceptor.There is wide spectrum preventive effect to lepidoptera pest.
Drug cost is higher when carbosulfan and chlorine fluorine cyanogen insect amide are used alone, and it is limited to a certain extent and is pushed away
Extensively apply, and long-term exclusive use easily causes pest resistance degree and is continuously increased.Therefore, by carbosulfan and chlorine fluorine cyanogen worm
Acid amides carries out mixture, is a kind of effective ways for preventing and treating agriculture resistant insect.
