Abstract
The invention relates to a desinsection composite with a synergy. The composite consists of emamectin benzoate and chlorfenapyr, which is composite with a weight ratio from1:1 to 1:100. The composite has the synergy cure the agricultural pests and solves the drug-fast problem of Cnaphalocrocis medinalis.
Description
Technical field
The present invention relates to a kind of composition pesticide, particularly relating to a kind of is active ingredient with emamection benaoate and chlorfenapyr, prevents and treats the insect on the agricultural, especially to the specific Pesticidal combination with synergistic function of paddy rice rice leaf roller.
Background technology
Emamection benaoate, be with the Avermectin be raw material through the product that chemical modification obtains, be a kind of insecticide of half synthetic, to common insect such as beet armyworm, diamond-back moth, cabbage caterpillar etc. has good control efficiency.
Chlorfenapyr is a kind of new type disinsection miticide, is used to prevent and treat agricultural and goes up important insect such as beet armyworm, and prodenia litura, diamond-back moth, cabbage caterpillar etc. also have good control efficiency to harmful mite common on the agricultural such as Tetranychus urticae, Tetranychus cinnabarinus etc.
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.Rice leaf roller is a kind of common insect of hazard rice, often Rice Production is caused major disaster.Prevent and treat main farm chemical ingredients such as the dimehypo of this worm, the desinsection list, acephatemet etc., these compositions or because long-term the use causes insect to produce high resistance, and preventive effect reduces, or owing to limiting use to higher mammal toxicity is too high.In recent years, causing harm of rice leaf roller, further increased the weight of.In some serious zone, the production loss that causes owing to causing harm of this worm can reach more than 80% of normal volume.
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.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 emamection benaoate and chlorfenapyr at present.
Summary of the invention
The objective of the invention is to solve the pesticide resistance problem of rice grub in the prior art, a kind of Pesticidal combination with synergistic function is provided.
For realizing purpose, technical scheme of the present invention is: a kind of Pesticidal combination with synergistic function is provided, it is made up of emamection benaoate and chlorfenapyr, the ratio of emamection benaoate and chlorfenapyr by mass ratio 1: 1-1: between 100.
Make different application forms during practical application, comprise missible oil, micro emulsion, water and milk, suspending agent, wetting powder.
The mass percentage content of emamection benaoate and the two accumulation of chlorfenapyr is between 1%-99%.
Below in conjunction with test beneficial effect of the present invention is described:
In order to prevent and treat the rice leaf roller on the paddy rice, we have carried out mutual composite synergy research with compositions such as emamection benaoate, chlorfenapyrs.The rice leaf roller in field is adopted in test, is used for test after raising.Concrete grammar is:
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 rice leaf roller pupa that picks up from the field, an indoor feeding generation, select the growth even one to third-instar larvae, the culture dish that the diameter of the access fresh rice leaf of storing (Shanyou 63, five leaf phases) is 9 centimetres, every ware connects 10, every processing connects six 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 67 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.Blank spray equivalent clear water.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.Result of the test sees Table 1
Table 1 different disposal is to the toxicity test result of rice leaf roller
| Handle | LC50(PPM) | Co-toxicity coefficient |
| Emamection benaoate 1+ chlorfenapyr 1 | 0.13 | 184.7 |
| Emamection benaoate 1+ chlorfenapyr 20 | 0.15 | 670.3 |
| Emamection benaoate 1+ chlorfenapyr 40 | 0.19 | 664.3 |
| Emamection benaoate 1+ chlorfenapyr 60 | 0.13 | 988.7 |
| Emamection benaoate 1+ chlorfenapyr 80 | 0.14 | 957.4 |
| Emamection benaoate 1+ chlorfenapyr 100 | 0.16 | 877.6 |
| Chlorfenapyr | 1.56 | |
| Emamection benaoate | 0.13 |
As seen from Table 1, emamection benaoate and chlorfenapyr are composite, and rice leaf roller is had very high synergistic effect.
