Abstract
The invention relates to a pesticide composition which is constituted by pyridaben and malathion and is used for controlling agricultural pests. The pesticide composition disclosed by the invention is particularly used for controlling the phyllotreta striolata of brassicaceous vegetables, wherein the phyllotreta striolata is resistant to organic phosphorous pesticides.
Description
The application is dividing an application of original application " contain pyridaben and organophosphorus insecticide are mixed have the composition of synergistic effect "; The application number of original application is 200710300253.0; On December 19 2007 applying date, the patent of invention name is called " contain pyridaben and organophosphorus insecticide are mixed have the composition of synergistic effect ".
Technical field
The composition pesticide that this invention relates to is to be active ingredient with pyridaben and organophosphorus insecticide (for example chlopyrifos, phoxim, dichlorvos, malathion etc.), prevents and treats the insect on the agricultural.Especially there is the flea beetle of resistance crop in cruciferae that special efficacy is arranged to organic phosphor.
Technical background
Pyridaben has another name called pyridaben, is a kind of heterocyclic miticide.To very high activity is all arranged each breeding time of Panonychus citri, tetranychid, goitre mite.All be used for using in China as miticide.Discover that through us pyridaben also has very high activity for flea beetle.Knock down rapidly, can alleviate at short notice causing harm of flea beetle.The pyridaben high-efficiency low-toxicity can be used for the production of pollution-free vegetable simultaneously.
Organophosphorus insecticide (comprising chlopyrifos, phoxim, dichlorvos, malathion etc.); The insecticide of this type mainly through suppressing the activity of the acetylcholinesterase in the insect bodies, conducts thereby destroy normal nerve impulse, causes the insect exaltation; Spasm, paralysis causes death at last.The mechanism of action is consistent, can cause insect to be prone to produce positive cross resistance.Present stage is insecticide more than 60% during China's agricultural chemicals uses, be organophosphorus insecticide more than 60% in the insecticide.Wherein produce the also most poisoning that causes for organophosphorus insecticide of incident such as pesticide poisoning.
In the real process of agricultural production, the problem that pest control is easy to generate most is the generation of pest resistance to insecticide.Flea beetle is claimed phyllotreta striolata again, also is a kind of common insect, and the main harm brassicaceous vegetable is often caused heavy losses.At southern china, flea beetle is annual to be taken place.At some serious zone takes place, commonly used being used to prevents and treats the medicament such as the dichlorvos of flea beetle, and phoxim etc. use also do not had what effect basically separately.Single organophosphorous pesticide of using needed use once in two to three days.Be unfavorable for the production of pollution-free vegetable.
Go up the insect 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 of new active ingredient is high, and the construction cycle is long, and all produces the speed of resistance less than insect forever.Other method such as crop allocation are adjusted, different agricultural chemicals is rotated etc., in the process of practical operation, are difficult to really play obvious effects.
The composition of different cultivars carries out composite, is control resistant insect or the very common way of evil mite.Heterogeneity is carried out composite, according to the effect of practical application, judge certain composite be synergy, add and or antagonism.Compound synergic is well filled a prescription, owing to obviously improved actual control efficiency, reduced the usage amount of agricultural chemicals, thereby delayed the generation of pest resistance to insecticide greatly, and be the important means of integrated control insect.Use at present pyridaben list agent control flea beetle or pyridaben with organic phosphorous insecticide is composite and application still nobody reported.
Summary of the invention
In order to prevent and treat the flea beetle that agricultural go up to produce resistance, we with pyridaben and chlopyrifos, phoxim, malathion, dichlorvos, quinalphos, etc. the organophosphorus insecticide composition carried out mutual composite synergy research.It is tested object that the phyllotreta striolata in field is adopted in test, and concrete grammar is:
The phyllotreta striolata test medicine is that producer provides former medicine, is mixed with the preparation that needs by research department.Non-resistant examination worm is the phyllotreta striolata adult of picking up from the field, after warm indoor cabbage heart seedling raised for five generations, selects the adult of growth uniformity; Resistance examination worm is directly picked up from the vegetable plot, field, organophosphorous pesticide has been produced the phyllotreta striolata adult of resistance.15 centimetres of the diameters of examination worm access storing cabbage heart blade are in the dark 30 centimetres cylinder.30 flea beetles of every socket joint.Bind up with gauze and continue to employ the osculum that can flea beetle be shaked out of rubber band tying below the cylinder.Under 50PSI pressure, aim at the cylinder internal spraying with the Potter spray tower.Cylinder of each spray, 5 milliliters of every spraying liquids.Sprayed and built above the cylinder, after static 10 minutes flea beetle has been shaked out from lower opening, with receiving medicine cabbage heart leaf to place 200 milliliters triangular flask to cultivate.Blank spray equivalent clear water.General each processing is provided with 6-7 concentration gradient.The triangular flask of handling is put into 25 ℃, cultivates in the 12H/12H illumination box, checks in 48 hours and to calculate lethality by dead borer population.Calculate the toxicity index of medicament and the co-toxicity coefficient of using with (CTC value) according to the abundant method of Sun Yun, CTC value greater than 100 be synergistic effect, equaling 100 is addition, is antagonism less than 100.
The mensuration result of flea beetle sees the following form respectively
