Abstract
An agricultural miticide is prepared from tebufenpyrad and abamectin.
Description
Technical field
The composition pesticide that this invention relates to is to be active ingredient with tebufenpyrad and Avermectin, prevents and treats the harmful mite on the agricultural.
Technical background
Tebufenpyrad is a kind of novel miticide rapidly and efficiently, and full phase of growth of various mite classes and mite is all had immediate effect and efficient, the lasting period is long, toxicity is low, do not have in absorption, but have permeability.
Avermectin also is a kind of common environment amenable insecticidal/acaricidal agent.Being a kind of macrolide antibiotics, is actinomycetic extract, has 16 kinds of isomer.The active component that is used as insecticidal/acaricidal agent mainly is Avermectin B1a and Avermectin B1b wherein, and the former is even more important again.On agricultural, Avermectin is control evil mite such as Tetranychus urticae, Tetranychus cinnabarinus etc. and the important kind of insect such as diamond-back moth, liriomyza bryoniae.
In the real process of agricultural production, the problem that pest control is easy to generate most is the drug-fast generation of insect evil mite.Important harmful mite is because its breeding cycle is short, and breeding amount is big, and mobility is little on the agricultural, and selfing degree height is easy to generate resistance especially.In some mite classes serious zone of causing harm, common miticide such as dicofol reach the mite spirit, and what effect use has not had separately.Avermectin is because large-area application has also caused very serious resistance.
Go up the harmful mite that produces resistance for control agricultural, a kind of way be release new do not have the new component of cross resistance with existing kind.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, different agricultural chemicals are 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.Still nobody reported in the composite and application of tebufenpyrad and Avermectin at present.
Summary of the invention
Go up the two spotted spider mite that produces resistance in order to prevent and treat agricultural, we have carried out mutual composite synergy research with compositions such as tebufenpyrad, Avermectin.It is tested object that Tetranychus urticae, the Tetranychus cinnabarinus in field are adopted in test, and compares with the sensitive strain of indoor feeding, and concrete grammar is:
1) the Tetranychus urticae test medicine provides former medicine for producer, is mixed with the preparation that needs by my research department of company.The examination worm is the female one-tenth mite of Tetranychus urticae of picking up from the field, through 6 generations of indoor feeding, select the one-tenth mite of growth uniformity, the culture dish that the diameter of access storing apple blade (red fuji apple, the moulding blade of New Development then) is 9 centimetres, every ware connects 30, every processing connects three wares, spray under 50PSI pressure with the POTT spray tower, spray a ware at every turn, 3 milliliters of every ware spraying liquids.Blank spray equivalent clear water.General each processing is provided with 5 concentration gradients.The culture dish of handling is put into 25 ℃, cultivates in the 12H/12H illumination box, checks the survival borer population in 48 hours, calculates the insect population rate that goes down.Calculate virulence equation and lethal concentration of 50 LC50 with method of least squares, 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.
2) the Tetranychus cinnabarinus test medicine provides former medicine for producer, is mixed with the preparation that needs by my research department of company.The examination worm is the female one-tenth mite of Tetranychus cinnabarinus of picking up from the field, through 6 generations of indoor feeding, select the one-tenth mite of growth uniformity, insert the culture dish of the diameter 9 casket rice of putting cotton leaf, every ware connects 30, and every processing connects three wares, sprays under 50PSI pressure with the POTT spray tower, ware of each spray, 3 milliliters of every ware spraying liquids.Blank spray equivalent clear water.General each processing is provided with 5 concentration gradients.The culture dish of handling is put into 25 ℃, cultivates in the 12H/12H illumination box, checks the survival borer population in 48 hours, calculates the insect population rate that goes down.Statistical method is the same.
3) measurement result of Tetranychus urticae, Tetranychus cinnabarinus see Table 1 respectively, table 2, table 3.Ratio is all by mass ratio
Table 1 different disposal is to the toxicity test result of Tetranychus urticae
