Embodiment 1

[0020] Example 1: Indoor toxicity test of tetramycin krysstrobin to pathogenic Rhizoctonia solani (Thanatephorus cucumeris).

[0021] The test objects were collected from the rice sheath blight in the field, and the method was referred to "The Agricultural Industry Standard of the People's Republic of China NY / T 1156.4-2006". According to Sun Yunpei's method, the synergistic effect of drug mixture is evaluated according to the co-toxicity coefficient (CTC), that is, CTC≤80 is synergistic antagonism, 8050 / EC of test agent 50 ) × 100; Theoretical toxicity index TTI = the toxicity index of A agent × the percentage content of A agent in the mixture + the toxicity index of B agent × the percentage content of B agent in the mixture; co-toxicity coefficient (CTC) =[Actual Toxicity Index (ATI) of Mixture / Theoretical Toxicity Index (TTI) of Mixture]×100

Embodiment 2

[0026] Embodiment 2: 12% Tetramycin·Kresstrobin Suspension Concentrate

[0027]

[0028]

[0029] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 12% tetramycin·kresstrobin suspension.

Embodiment 3

[0030] Example 3: The combination of tetramycin and kresoxim-methyl control rice sheath blight.

[0031] Spray with water at the initial stage of rice sheath blight discovery, and the control effect 10 days and 20 days after the application: 0.1% tetramycin·11.9% kresoximin SC 45g a.i. / ha control effect 92.71%, 85.02%; 0.15% tetramycin The control effect of 1.35g a.i. / ha of plain water agent is 83.52%, 79.40%; the control effect of 90g a.i. / ha of 30% kresoxim-methyl suspension concentrate is 87.40%, 81.57%.

[0032] The effect of the combination of tetramycin and kresoxim-methyl for preventing and treating rice sheath blight is obviously better than that of tetramycin and kresoxim-methyl alone. The environmental load is reduced, the use cost is reduced, and a more effective management tool for rice sheath blight is provided for farmers.

Abstract

The invention discloses a sterilization composition containing tetramycin and kresoxim-methyl. The sterilization composition comprises an inert ingredient, the tetramycin and the kresoxim-methyl; the ratio of the parts by weight of the tetramycin to the kresoxim-methyl ranges from 1:1 to 1:80, and the total weight of the tetramycin and the kresoxim-methyl in the composition ranges from 1% to 80%; the tetramycin and the kresoxim-methyl have the obvious synergistic interaction effect on pathogen fungi after being compounded, and the pesticide composition is suitable for preventing and treating crop diseases caused by the pathogen fungi, and is particularly suitable for preventing and treating a rice sheath blight disease caused by rhizoctonia solani.

Description

technical field [0001] The fungicidal composition involved in the present invention uses tetramycin and kresoxim-methyl as active ingredients, and is suitable for preventing and treating crop diseases caused by pathogenic fungi, especially rice sheath blight caused by Rhizoctonia solani (Thanatephorus cucumeris) pathogens sick. Background technique [0002] Tetramycin is a biopesticide produced by Streptomyces ahygroscopicus subsp.Wuzhouensis n.subsp through submerged fermentation of strains. It induces crop resistance by inhibiting the growth of hyphae and promotes crop resistance. It grows to achieve the purpose of prevention and control, and is suitable for the prevention and control of various fungal and bacterial diseases of various forest trees. [0003] Kresoxim-methyl has a strong inhibitory effect on the germination of spores and the growth of mycelium in leaves. It has protection, treatment and eradication activities, good penetration and local systemic activity, ...
