Abstract
The invention discloses a pesticide composition with active ingredients being pyraclostrobin and propamidine. The pesticide composition contains a commonly-used auxiliary agent, pyraclostrobin and propamidine. Weight ratio of pyraclostrobin to propamidine is 20:1-1:20. The total weight of pyraclostrobin and propamidine in the pesticide composition is 3-90 wt%. After pyraclostrobin and propamidine are compounded, the pesticide composition has an obvious synergistic effect, and dosage of the active ingredients of the compounded medicine is obviously reduced in comparison with dosage of each active ingredient which is used separately. The pesticide composition is applicable to control crop diseases caused by pathogenic fungi, especially crops' gray mold caused by Botrytis pathogen and crops' gibberellic disease caused by Gibberella pathogen.
Description
Technical field
The present invention relates to a kind of composition pesticide, specifically a kind of composition pesticide containing pyraclostrobin and propamidine.
Background technology
Pyraclostrobin; english common name Pyraclostrobin; for methoxy acrylic series bactericidal agent; for mitochondrial respiratory inhibitor; namely by stoping electro transfer in cytochrome synthesis; have protection, treatment, blade infiltration conduction, preventing and treating powdery mildew of cucumber, downy mildew and banana freckle, leaf spot, stalk break etc. has good control efficiency.
Propamidine, english common name Propamidine, belongs to aromatic diamidino compounds; propamidine is systemic fungicide; in plant body absorption, distribution and metabolism, protection and therapeutic action can be had, be mainly used in preventing and treating the crop gray mold caused by Botrytis pathogen.
The mixture of different pesticide species is the common methods of preventing and treating agriculture resistance disease.Screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reducing costs, delay the generation of disease drug resistance, is the important means of the disease comprehensive regulation.
Pyraclostrobin and the composite protective effect enhanced crop of propamidine, reduce the resistance risk being used alone pyraclostrobin or propamidine and bringing simultaneously, has no pyraclostrobin and the composite report of propamidine at present.
Summary of the invention
The technical problem that the present invention solves be to provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the composition pesticide containing pyraclostrobin and propamidine of the disease comprehensive regulation.
For solving the problem, the technical solution adopted in the present invention is: a kind of composition pesticide containing pyraclostrobin and propamidine, comprise usual auxiliaries and pyraclostrobin and propamidine, pyraclostrobin and propamidine ratio of weight and number are 20:1 ~ 1:20, and pyraclostrobin and the percentage by weight of propamidine weight summation in composition pesticide are 3% ~ 90%.
Further: the above-mentioned composition pesticide containing pyraclostrobin and propamidine can according to well known to a person skilled in the art method, adopt suitable insecticides adjuvant, be configured to suspending agent, dispersible oil-suspending agent, water dispersible granules, wetting powder etc. are applicable to the formulation that agriculturally uses.
The insecticides adjuvant used in composition pesticide of the present invention comprises solvent, emulsifier, wetting agent, disintegrant, stabilizing agent, dispersant, thickener, penetrating agent, pH adjusting agent, defoamer, antifreezing agent, carrier etc., and to be of value to active ingredient stable and play the known substance of drug effect in the formulation, be all various compositions that are conventional in pesticidal preparations or permission use, concrete composition and consumption are determined by test according to recipe requirements.
The frequency of administration of composition pesticide of the present invention and amount of application change with crops, insect, weather condition and have small variations, can by the object using suitable dosage reach effectively control.
Compared with prior art, the invention has the advantages that:
1, the control efficiency of composition pesticide of the present invention is significantly improved than single dose, reduces the using dosage of agricultural chemicals, reduces cost.
2, the active ingredient mechanism of action of composition pesticide of the present invention is different, and the application of composition can delay or overcome the drug-fast generation of germ, is conducive to the comprehensive regulation.

Embodiment 5.
For understanding the synergy type of pyraclostrobin and propamidine mixture further, the present inventor has carried out a large amount of Toxicity Determination tests to pyraclostrobin and propamidine mixture.
According to the abundant method of Sun Yun, the synergy of pharmacy mix is evaluated according to co-toxicity coefficient (CTC), namely CTC≤80 are joint action of antagonism, and 80 < CTC < 120 are joint action of antagonism, and CTC >=120 are synergistic function.
Actual measurement toxicity index (ATI)=(EC50 of the EC50/ reagent agent of standard agent) × 100;
In the toxicity index × mixture of theoretical toxicity index TTI=A medicament the percentage composition+B medicament of A medicament toxicity index × mixture in the percentage composition of B medicament;
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100.
(1) Toxicity Determination of Botrytis cinerea (Botrytis cinerea) is tested.
Subjects picks up from the graw mold of tomato pathogen Botrytis cinerea (Botrytis cinerea) in field, method reference " People's Republic of China (PRC) agricultural industry criteria NY/T1156.6-2006 ", mycelial growth rate method.
Table 1, pyraclostrobin propamidine are to the Toxicity Determination result of Botrytis cinerea (Botrytis cinerea).
As shown in Table 1, pyraclostrobin and propamidine mixture are between 20:1 ~ 1:20, and have obvious synergistic effect to Botrytis cinerea (Botrytis cinerea), co-toxicity coefficient is all more than 150.
(2) to the Toxicity Determination of Gibberella zeae bacterium (Gibberella zeae).
Subjects is the wheat scab pathogen Gibberella zeae bacterium (Gibberella zeae) of picking up from field, and method is with reference to " People's Republic of China (PRC) agricultural industry criteria NY/T1156.6-2006 " growth rate method.
Table 2, pyraclostrobin propamidine are to the Toxicity Determination result of Gibberella zeae bacterium (Gibberella zeae).
As shown in Table 2, pyraclostrobin and propamidine mixture are between 20:1 ~ 1:20, and have obvious synergistic effect to Gibberella zeae bacterium (Gibberella zeae), co-toxicity coefficient is all more than 150.
In sum, the control efficiency of composition pesticide of the present invention is significantly improved than single dose, reduces using dosage and the cost of manufacture of agricultural chemicals.Therefore pyraclostrobin and propamidine mixture have reasonability and feasibility.
