A kind of bactericidal composition containing boscalid and its application

Abstract

The invention belongs to the technical field of pesticides, and discloses a boscalid-containing fungicidal composition and application thereof. The fungicidal composition takes validamycin, metconazole and boscalid as active ingredients, wherein the weight ratio of validamycin to metconazole to boscalid is (1-20):(1-28):(1-40). The fungicidal composition has the obvious synergistic effect on prevention and control over soybean rust, kidney bean rust, pear rust, wheat head blight, wheat powdery mildew, wheat rust, wheat sheath blight, wheat leaf blight, rice blast, rice false smut and rice sheath blight and particularly has the more obvious effect on prevention and control over the soybean rust, the kidney bean rust and the pear rust. According to the fungicidal composition, the dosage and dosing frequency can be significantly decreased in agricultural production, the production cost is reduced, environmental pollution is reduced, pesticide residues are decreased, and the important practical significance is achieved on increasement of the social, economic and ecological benefits.

Description

technical field

[0001] The invention relates to a ternary bactericidal composition containing Jinggangmycin, metconazole and boscalid and its application, which belongs to the fungicide composition with synergistic and weight-reducing effects in the technical field of pesticides, and its active ingredient is Jinggangmycin Metconazole and boscalid. Background technique

[0002] Jinggangmycin, also known as validamycin, English common name: Validamycin or jinggangmycin, its chemical structural formula is as follows:

[0003]

[0004] Jinggangmycin is a secondary metabolite of actinomycetes, containing A, B, C, D, E, F six similar aminoglucoside derivatives. A large number of studies at home and abroad have shown that component A is the main active component of Jinggangmycin. Therefore, the main component of Jinggangmycin involved in the present invention is Jinggangmycin A. Jinggangmycin specifically interferes with the development of apical hyphae of Rhizoctonia spp. in...

Examples

Embodiment 1

[0028] Example 1: 44% Jinggangmycin Metconazole Boscalid WP

[0029] Jinggangmycin 16%, metconazole 8%, boscalid 20%, sodium dodecylbenzene sulfonate 3%, NNO-1 1%, tea dry powder 2%, attapulgite 25%, and the rest Diatomaceous earth supplemented to 100%. The above components were thoroughly mixed, pulverized by a sand mill and passed through a 300-mesh sieve to obtain a 44% Jinggangmycin·Meconazole·Boscalid wettable powder.

Embodiment 2

[0030] Example 2: 20% Jinggangmycin Metconazole Boscalid WP

[0031] Jinggangmycin 8%, metconazole 8%, boscalid 4%, sodium dodecylbenzene sulfonate 3%, NNO-1 1%, tea dry powder 2%, attapulgite 25%, the rest is Diatomaceous earth supplemented to 100%. The above components are fully mixed, pulverized by a sand mill and passed through a 300-mesh sieve to obtain a 20% Jinggangmycin·Meconazole·Boscalid wettable powder.

Embodiment 3

[0032] Example 3: 54% Jinggangmycin Metconazole Boscalid WP
