Description
Technical field
The present invention relates to technical field of pesticide, particularly relate to a kind of composite insecticide and the application thereof that contain cycloxaprid.
Background technology
Rice leaf roller belongs to Lepidoptera Pyralidae, is one of exogenous insect of paddy rice.Rice plant of tillering stage is injured affects its normal growth; Middle and later periods is injured, and affects output more obvious, and particularly sword-like leave is injured the later stage, and cause not plump paddy rate to increase, loss seriously.Adult is hidden by day and come out at night, and has light, becomes green and characteristic of trooping.Ovum is loose to be originated on blade, and be many with blade back usually, newly hatched larvae is climbed to blade tip leaf roll and taken food, and slightly large larva then pierces on the interior or blade face of the leaf heart, leaf sheath and stings food mesophyll, and weaves silk the both sides of leaf are indulged clove hitch bud.Tie good bud rear just suitable vein food mesophyll and epicuticle in bud, killed leaf presents strip tikka different in size.After larva is aging, again ties bud in plant bottom and leaf sheath portion and pupate.A larva edible harmful 5-9 sheet leaf in all one's life, it is in vain withered that killed serious field presents a slice.In recent years along with high yield, the popularization of Japonica rice kind and the change of cropping system, habitat and Feeding Condition are all better, and therefore rice leaf roller breeds soon, survival rate is high, is on the rise to rice hazard.Production prevents and treats pharmacopoeia, and be only suitable for preventing and treating 1-2 instar larvae, the lasting period is short, and to large instar weak effect, peasant needs repeatedly dispenser, just can control its harm.Therefore, be badly in need of developing the compound drug that a kind of quick-acting is good, the lasting period is long, reduce the number of times of field medication, maintaining ecological balance, alleviates environmental pollution.
Cycloxaprid is a kind of new and effective, wide spectrum, low toxicity nicotinic insecticide, the domestic kind with independent intellectual property right, activity is high, mechanism of action new, highly active nAChR antagonist, be mainly used in preventing and treating homoptera pest, have good control efficiency to rice fulgorid.
Emamectin benzoate (EmamectinBenzoate) is also known as emamectin-benzoate, and molecular formula is C
56h
81nO
15, molecular weight is 1008.24, and be the new and effective semisynthetic antibiotics insecticide of one of synthesis from fermented product AVERMECTIN B1, its mechanism of action and Avermectin are substantially the same, is hinder pest movements nerve information transmission and make polypide benumb death equally.To the larva of lepidopterous insects and the activity of other many insect high, existing stomach poison function is double action of contace poison again, under low-down dosage, there is good effect, reach most high mortality after dispenser in 3-4 days, due to it and soil combine closely, not leaching, also do not accumulate in the environment, very easily absorbed by crops and penetrate into epidermis, make dispenser crop have long-term residual effect, more than 10 days, occur second desinsection lethality rate peak again, seldom affect by environmental factor such as wind, rain etc. simultaneously.This product is widely used in the control of the various pests on the crops such as paddy rice, vegetables, fruit tree, cotton.
At present, due to the popularization of single-dose product, insect is strengthened just gradually to active component pesticide resistance.For the control of insect agriculturally easily producing resistance, what main way was exploitation and existing kind without between the new component of cross resistance or existing pesticide species is composite, the former is because required development cost is high, the cycle is long, and current development rate is far away less than the speed that pest resistance to insecticide produces.Therefore, carrying out mixture for the existing pesticide species that the mechanism of action is different is best selection.If reasonable mixture ratio, then can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose.Certain defect is usually there is in the insecticide containing single-activity composition on agricultural insect pests control, continuous several times uses and not only makes insect easily develop immunity to drugs, and easily cause the pollution to food and environment, above shortcoming can be overcome by rational mixture between pesticide active ingredient.The simultaneously reasonably composite synergistic effect that active ingredient is produced, can improve preventive effect, minimizing effective ingredient consumption, cost-saving, delays the drug-fast generation of insect, and then can alleviate the pollution even avoiding agricultural chemicals to food and environment.
Tie up plain different insecticidal mechanism according to cycloxaprid and first, its perfect adaptation got up, be aided with suitable auxiliary agent and carrier, seek most suitable proportioning to improve insecticidal effect, the research slowing down the generation of pest resistance to insecticide is worth research.
