Abstract
The invention discloses a pesticide combination comprising the active ingredients including fenazaquin and tebufenpyrad in a mass ratio of 60:1-1:60. By combining the fenazaquin and the tebufenpyrad,the combination has obvious synergy effect, can reduce the dosage of the active ingredients and the pesticide application frequency, and is conductive to retarding the drug resistance of mites. The combination of the invention can be used for controlling various mites on the crops and the horticultural crops, is especially suitable for controlling panonychus ulmi, tetranychus cinnabarinus and tetranychus urticae koch and can simultaneously control homopteran and hemiptera pests on the crops.
Description
Technical field
The present invention relates to a kind of composition pesticide, be specially the composition pesticide that contains fenazaquin, and the application of said composition in agricultural and the control of horticultural crop mite pest.
Background technology
Mite pest easily develops immunity to drugs to miticide because of its generation is many from generation to generation, fertility strong, selfing degree height.And the peasant gets used to single kind of miticide using miticidal effect good continuously, and the result causes multiple miticide to produce serious resistance in a short period of time and loses value.Adopting the miticide of the different mechanisms of action composite is to solve the evil mite easily to produce resistance, one of efficient, acaricidal effective way of sustainable use.
Fenazaquin (Fenazaquin) belongs to the quinolines miticide, and orange tree, apple tree two spotted spider mite are had the better prevention effect, and the lasting period is long, to natural enemies security.Do not have cross resistance with existing miticide, be particularly suitable for preventing and treating the pest mite class that existing miticide is produced resistance.But fenazaquin is the same with other miticides, is easy to generate resistance, and single agent control evil mite cost is higher relatively.
Tebufenpyrad (tebufenpyrad) belongs to the amide-type miticide.Various mite classes and Semiptera, homoptera pest are had tall and erect the effect, and all have immediate effect with efficient the dawn each vegetative period to the mite class, the lasting period is long.Absorption in not having, but osmotically active is arranged.
Summary of the invention
The objective of the invention is to:
A kind of miticide composition with synergistic effect is provided, is used for the improvement of evil mite on agricultural and the horticultural crop, delay the drug-fast generation of evil mite, improve control efficiency.
The present invention is achieved through the following technical solutions:
A kind of composition pesticide, active ingredient are fenazaquin and tebufenpyrad, and the mass ratio of fenazaquin and tebufenpyrad is 60: 1-1: 60.
Described composition pesticide, needs according to agriculture control of pest mite, active ingredient is added auxiliary agent and excipients make agricultural according to known production technology and go up available any formulation, preferred dosage form is missible oil, suspending agent, oil-suspending agent, wetting powder and water dispersible granules.
As a kind of improvement of the present invention, the mass ratio of fenazaquin and tebufenpyrad is preferably 30: 1-1: 20.
Composition pesticide of the present invention is used for the control of multiple harmful mite on agricultural and the horticultural crop, is particularly useful for the control of Panonychus citri, Tetranychus cinnabarinus and Tetranychus urticae.
Compare with prior art, beneficial effect of the present invention is: 1, two kinds of active ingredient is composite in the composition has an obvious synergistic effect, can reduce effective ingredient consumption, reduces spraying times; 2, the miticide of the different mechanisms of action is composite, and the notable synergistic effect is arranged, and reduces the selection pressure to the evil mite, delays the drug-fast generation of evil mite.

With the panonychus citri is subjects, employing leaf dish spray-on process (with reference to " NY/T1154.13-2008 agricultural chemicals indoor bioassay test rule insecticide. the 13rd part: leaf dish spray-on process "), the synergistic effect size of mensuration fenazaquin and the composite different proportion of tebufenpyrad.Less culture dish back-off in the bigger culture dish that fills suitable quantity of water, be covered in little culture dish bottom with a gauze, the gauze edge immerses in the big culture dish water, obtain tomato leaf and place on the gauze beating with puncher, the normal panonychus citri of picking 30 head growths is on blade, be placed on spraying under the spray tower, and place observation in the culturing room, 48 hours observed results.Co-toxicity coefficient (CTC value) according to the abundant method calculation composition of Sun Yun:
Actual measurement toxicity index (ATI)=(standard medicament LC
50/ reagent agent LC
50) * 100
The percentage composition of B in percentage composition+B medicament toxicity index * mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixture
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (the ATI)/theoretical toxicity index (TTI) of mixture] * 100
When CTC≤80, then the composition performance is for antagonism, and when 80＜CTC＜120, then the composition performance is for summation action, and when CTC 〉=120, then the composition performance is synergistic effect.
