Abstract
The present invention relates to a pesticide composition composed of Diafenthiuron and one of or both following two components: 1, fenpropathrin; 2, high-efficiency cypermethrin. The composition is used for preventing and curing pest and acarus, particularly suitable for preventing and curing Tetranychus urticae Koch and diamond back moth having fastness to pesticide such as pyrethrins.
Description
Technical field
The composition pesticide that this invention relates to is to be active ingredient with butyl ether urea and fenpropathrin or beta-cypermethrin, prevents and treats insect and evil mite on the agricultural.
Technical background
The butyl ether urea is a kind of Thiourea insecticidal/acaricidal agent, is used to prevent and treat agricultural and goes up important harmful mite such as Tetranychus urticae, Tetranychus cinnabarinus etc., prevents and treats important insect such as diamond-back moth, cabbage caterpillar, prodenia litura, aphid etc.Facts have proved that this composition not only control efficiency is good, and environmentally friendly.
Fenpropathrin is a kind of common pyrethroid insecticidal/acaricidal agent.Have tag, stomach poison function, be widely used in the various pests on the crops such as control cotton, fruit tree, tea tree, vegetables, as the diamond-back moth of harm brassicaceous vegetable, the cotton bollworm of harm cotton etc.
Beta-cypermethrin is a kind of common pyrethroid insecticides.Have tag, stomach poison function, be widely used in the various pests on the crops such as control cotton, fruit tree, tea tree, vegetables, as the diamond-back moth of harm brassicaceous vegetable, the cotton bollworm of harm cotton etc.Beta-cypermethrin, it is the mixture of two pairs of racemic modifications of cypermethrin, i.e. (S)-a-cyano group-3-phenoxy benzyl (1R, 3R)-3-(2, the 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester and (R)-a-cyano group-3-phenoxy benzyl (1S, 3S)-3-(2, the 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester with (S)-a-cyano group-3-phenoxy benzyl (1R, 3S)-3-(2, the 2-dichloroethylene)-2, and 2-dimethyl cyclopropane carboxylic acid ester and (R)-a-cyano group-3-phenoxy benzyl (1S, 3R)-3-(2, the 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester.
Yet 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.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.
Diamond-back moth is a kind of common insect, and the main harm brassicaceous vegetable is often caused crushing disaster.Especially in the zone, south, diamond-back moth is annual takes place.In some serious zone, the Methomyl of the sumicidin in conventional pesticide composition such as the pyrethroid, the phoxim in the organic phosphor, carbamates etc., separately control is almost without any effect.
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 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.In most cases, the composite effect of agricultural chemicals all is an additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Now, in the composite research of agricultural chemicals, also can't be, add and still be that antagonism is predicted to the synergy of composite back, can not carry out theoretic explanation to the result.
Summary of the invention
Go up the diamond-back moth that produces resistance in order to prevent and treat agricultural, we have carried out mutual composite synergy research with compositions such as butyl ether urea, fenpropathrin, beta-cypermethrins.It is tested object that the diamond-back moth in field is adopted in test, and compares with the sensitive strain of indoor feeding, and concrete grammar is:
1) the diamond-back moth test medicine provides former medicine for producer, is mixed with the preparation that needs by research department of the general letter of promise company.The examination worm is the pickles chrysalis of picking up from the field, an indoor feeding generation, select the third-instar larvae of growth uniformity, the culture dish that the diameter of access storing cabbage leaf (black leaf Chinese cabbage, outermost layer blade) 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.General each processing is provided with 6-7 concentration gradient.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.Blank spray equivalent clear water, the sensitivity examination worm of contrast is the indoor long-term raising in laboratory, without any chemicals treatment, the length of time is consistent with above-mentioned examination worm.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 urticae test medicine provides former medicine for producer, is mixed with the preparation that needs by research department of the general letter of promise company.The examination worm is the female one-tenth mite of Tetranychus urticae of picking up from the field, through indoor feeding, select the one-tenth mite of growth uniformity, insert the culture dish of the diameter 9 casket rice of putting apple blade (red fuji apple, the moulding blade of New Development then), 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, the sensitivity examination worm of contrast is the indoor long-term raising in laboratory, without any chemicals treatment, the length of time is consistent with above-mentioned examination worm.General each processing is provided with 6-7 concentration gradient.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) the Tetranychus cinnabarinus test medicine provides former medicine for producer, is mixed with the preparation that needs by research department of the general letter of promise company.The examination worm is the female one-tenth mite of Tetranychus cinnabarinus of picking up from the field, through indoor feeding, select the one-tenth mite of growth uniformity, the culture dish that the diameter of access storing cotton leaf is 9 centimetres, 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, the sensitivity examination worm of contrast is the indoor long-term raising in laboratory, without any chemicals treatment, the length of time is consistent with above-mentioned examination worm.General each processing is provided with 6-7 concentration gradient.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.
4) to the measurement result of diamond-back moth, Tetranychus urticae, Tetranychus cinnabarinus see Table 1 respectively, table 2, table 3.R represents resistance examination worm, and S represents responsive examination worm.
