Description
Technical field
The present invention relates to a kind of composition pesticide, specifically a kind of pesticide combination containing Fluoxastrobin and propamidine
Thing.
Background technology
Fluoxastrobin, english common name Azoxystrobin, it is methoxy acrylic series bactericidal agent, Fluoxastrobin is line
Plastochondria respiration inhibitor, i.e., by preventing electronics from shifting in being synthesized in cytochromes, there is protection, treatment, blade infiltration conduction
Effect, efficient, wide spectrum, to almost all of mycota, (Ascomycotina, Basidiomycotina, Mastigomycotina and Fungi Imperfecti are sub-
Door) disease such as powdery mildew, rust, glume blight, net blotch, downy mildew, rice blast etc. has good activity, sprayed available for cauline leaf
Mist, seed treatment, it can also carry out soil treatment.
Propamidine, english common name Propamidine belong to aromatic diamidine compound, and propamidine is sterilized for absorbability
Agent, can have protection and therapeutic action in plant body absorption, distribution and metabolism, be mainly used in preventing and treating by Botrytis cause of disease
Crop gray mold caused by thing.
The mixture of different pesticide species, it is the common methods for preventing and treating agriculture resistance disease.Screened, screened by formulation of pesticide
Go out rational formula, actual prevention effect can be effectively improved, reduce dosage, reduce cost, delay the generation of disease drug resistance,
It is the important means of the disease comprehensive regulation.
Fluoxastrobin and propamidine compounding enhance the protective effect to crop, while reduce and Fluoxastrobin or propane is used alone
The resistance risk that amidine brings, Fluoxastrobin and the report of propamidine compounding are had no at present.
The content of the invention
The technical problem that the present invention need to solve be to provide it is a kind of efficiently, low toxicity, quick-acting is good and lasting period length, be advantageous to disease
The composition pesticide containing Fluoxastrobin and propamidine of the evil comprehensive regulation.

Embodiment 5.
To further appreciate that the synergy type of Fluoxastrobin and propamidine mixture, the present inventor is to Fluoxastrobin and propamidine
Mixture has carried out substantial amounts of Toxicity Determination experiment.
According to the abundant methods of Sun Yun, the synergy of pharmacy mix is evaluated according to co-toxicity coefficient (CTC), i.e. CTC≤80 are association
Same antagonism, 80 ＜ CTC ＜ 120 are joint action of antagonism, and CTC >=120 are synergistic function.
Survey toxicity index (ATI)=(EC of standard agent50The EC of/reagent agent50)×100；
The virulence of the percentage composition+B medicaments of A medicaments refers in toxicity index × mixture of theoretical toxicity index TTI=A medicaments
The percentage composition of B medicaments in number × mixture；
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
(1) Toxicity Determination of Botrytis cinerea (Botrytis cinerea) is tested.
Subjects pick 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, Fluoxastrobin propamidine are to Botrytis cinerea (Botrytis cinerea) Toxicity Determination result.
As shown in Table 1, Fluoxastrobin and propamidine mixture are 25:1~1:Between 7, to Botrytis cinerea (Botrytis
Cinerea) there is obvious synergistic effect, co-toxicity coefficient is more than 150.
(2) Toxicity Determination of phytophthora infestans (Phytophthora infestans) is tested.
Subjects are to pick up from the late blight of potato pathogen phytophthora infestans (Phytophthora in field
), infestans method reference《People's Republic of China (PRC) agricultural industry criteria NY/T1156.6-2006》Growth rate method.
Table 2, Fluoxastrobin propamidine are to phytophthora infestans (Phytophthora infestans) Toxicity Determination knot
Fruit.
As shown in Table 2, Fluoxastrobin and propamidine mixture are 25:1~1:Between 7, to phytophthora infestans (Phytophthora
Infestans) there is obvious synergistic effect, co-toxicity coefficient is more than 150.
In summary, Fluoxastrobin mixes and shows obvious synergistic effect in different proportions with propamidine, composition
Prevention effect is significantly improved than single dose, reduces the dosage of agricultural chemicals, reduces cost, and mixture has reasonability and can
Row.
