Abstract
The invention discloses an anti-mite composition. The anti-mite composition comprises active ingredients including avermectin and bifenazate, wherein the weight ratio of avermectin to bifenazate is 10:1-1:20. With compounding of avermectin and bifenazate, the anti-mite composition is used for controlling pets and pest mites in agriculture and particularly has remarkable effect of controlling citrus red mites.
Description
Technical field
The present invention relates to the technical field of composition pesticide, be specially a kind of miticide composition.
Background technology
Avermectin, English name Avermectins, be that the class first developed by Japanese North university large village intelligence etc. and Merck company of the U.S. has desinsection, kills mite, ten hexa-atomic Macrocyclic lactone compounds of eelworm-killing activity, it is tagged, stomach toxicity, and penetration is strong.Avermectin is the natural products be separated from edaphon, have insects and mites tag, stomach toxicity and faint fumigation action, without systemic action, but it has very strong osmosis to blade, can kill subepidermal insect.
Bifenazate, Bifenazate, English name bifenazate, Bifenazate is a kind of new selective foliar spray miticide.Its mechanism of action is the unique effect of an aminobutyric acid (GABA) acceptor to the nervous centralis conducting system of mite class.It is effective to each life stage of mite, have ovicidal activity and knock down activity (48 ~ 72h) with to what become mite, and the lasting period is long.Lasting period about 14d, to crop safety in recommendation dosage range.To parasitic wasp, Predatory Mites, Chrysopa low-risk.
Mite class, has another name called two spotted spider mite, white spider etc., belongs to Arthropoda arachnids.Panonychus citri, Tetranychus cinnabarinus, Tetranychus urticae, goitre mite and rust mite is mainly contained in the mite class of agriculturally damage to crops, it is large that the mite class of these damages to crops has egg laying amount usually, reproduction speed is fast, population density is large, and generation overlap is obvious, and the feature such as easily develop immunity to drugs, usually fruit flower skin is caused, leaf chlorosis, fruit tree nutrition is bad, finally occurs falling flower, falls leaf, falls the destructive consequences such as fruit.
In the process of China's agricultural production, chemical control is the main effective means of control mite class, but adopts this prevention and controls mite class easily to develop immunity to drugs, especially panonychus citri, and under the environmental condition of long-term prescription, resistance increases obviously.Thus the miticides such as pyridaben, azacyclotin, Hexythiazox, clofentezine are used alone, the harm of uncontrollable mite class.The composition of different cultivars carries out composite, is to prevent and treat resistant insect or do harm to the very common way of mite
Summary of the invention
The object of the invention is to according to above-mentioned Problems existing, and provide a kind of miticide composition, said composition can prevent and treat insect agriculturally, harmful mite is especially remarkable to citrus red mite control efficiency.
Technical scheme of the present invention is: active ingredient is Avermectin and Bifenazate, it is characterized in that, in said composition, the weight ratio of Avermectin and Bifenazate is 20:1 mono-1:20, as preferably, described Avermectin and the weight ratio of Bifenazate are Avermectin: Bifenazate=1:1-1:10.
The weight percentage of described active ingredient is 1%-85%, and namely total both Avermectin and Bifenazate weight percentage is 1%-85%, and preferred active ingredient weight percentage is 1%-30%.
Described combination dosage form comprises missible oil, aqueous emulsion and suspending agent, making different formulations, meeting different occasion needs according to being equipped with agricultural chemicals used additives and excipients etc. during practical application.
The present invention can be used for desinsection, kills mite, kills nematode, especially remarkable to diamond-back moth, rice leaf roller, citrus red mite, root knot nematode control efficiency.
Beneficial effect of the present invention is: the present invention can prevent and treat insect agriculturally, harmful mite, harmful nematode etc., synergistic effect is good, significantly improve actual control efficiency, reduce the usage amount of agricultural chemicals, thus delay the generation of pest resistance to insecticide greatly, for current single dose uses resistance problems to provide good solution, also reduce the residue of pesticide of product, Product Green environmental protection, simultaneously, further alleviation, to the pollution problem of environment, meets the trend of future society environmental protection.Said composition has desinsection, kills mite, nematicide effect, especially remarkable to diamond-back moth, rice leaf roller, citrus red mite, root knot nematode control efficiency.
Study compound synergic of the present invention, test adopts the two spotted spider mite in field.
Concrete grammar is: adopting commercially available former medicine to carry out composite is required preparation.Examination worm is the two spotted spider mite of picking up from field, and select the larva of growth uniformity, in the culture dish of the diameter 9 centimetres of access, every ware connects 30, and often process connects three wares, sprays under SOPSI pressure with POTT spray tower, each spray ware, every ware spraying liquid 3 milliliters.General each process arranges 1-7 concentration gradient.The culture dish processed puts into 25 DEG C, cultivates in 12H/l2H illumination box, within 48 hours, checks survival borer population, calculates Revision insect recluced rate.Blank spray equivalent clear water.Calculate virulence equation and lethal concentration of 50 LC50 by method of least squares, calculate toxicity index and the mixed co-toxicity coefficient (CTC value) of medicament according to the abundant method of Sun Yun.
Table one: different ratio relation is to the toxicity test result of citrus red mite
