Problems solved by technology

It occurs to varying degrees in the southern and northern rice regions of my country. In the popular year, the yield is generally reduced by 10-20%, and the severe reduction is as high as 40-50%. It is in the shape of fire. Although some rice plants do not die, the new leaves drawn out are not easy to elongate. The plants shrink and do not head or pull out short ears. The disease occurs during the booting and heading stage, and severe knot blast and neck blast occur, which can cause a large number of white ears or half white ear, great loss

Embodiment 1

[0028] Example 1: Indoor toxicity test of tetramycin·fluxazone against pathogenic rice pear spore (Pyricularia oryzae Cav.).

[0029] The test object was collected from the rice blast in the field, and the method was referred to the "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". 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

[0034] Example 2: 10% tetramycin·fluxazone suspension.

[0035]

[0036]

[0037] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 10% tetramycin·fluxazone suspension.

Embodiment 3

[0038] Example 3: 10% tetramycin·fluxazone microemulsion.

[0039]

[0040] Dissolve fluvaxamin with acetone first, then add methanol, 602, MP-10, tetramycin, and deionized water in sequence, each single material needs to be stirred for 20 minutes before adding, and 10% tetramycin·fluxazone can be made cycloheximide microemulsion.

Abstract

The invention discloses a pesticide composition containing tetramycin and fenfluxamin, including pesticide adjuvants, tetramycin and fenfluxamin, and the ratio of tetramycin to fenfluxamin in parts by weight It is 1:1~1:80, and the weight percentage of the sum of tetramycin and fenfluxamin in the composition is 1%~80%; The fungus has obvious synergistic effect, and is suitable for preventing and controlling crop diseases caused by pathogenic fungi, especially rice blast caused by Pyrosporium oryzae.

Description

technical field [0001] The bactericidal composition of the present invention uses tetramycin and fenfluxamin as active ingredients, and is suitable for preventing and treating crop diseases caused by Pyricularia oryzae Cav., especially rice blast. Background technique [0002] Tetramycin is a biopesticide produced by Streptomyces ahygroscopicus subsp.Wuzhouensis n.subsp through submerged fermentation of strains. It induces crop resistance and promotes crop growth by inhibiting the growth of hyphae. To achieve the purpose of prevention and control, it is suitable for the prevention and control of various fungi and bacterial diseases of various forest trees. [0003] Fluxazone is a systemic fungicide, which can inhibit the normal respiratory process of target pathogenic bacteria, and has good therapeutic and protective effects. [0004] Rice blast is one of the four major diseases of rice. It is caused by Phyricularia grisea (Cooke) Sacc. Pyricularia oryae Cav. [0005] Rice...
