Problems solved by technology

However, due to long-term use of the same chemical agent, the resistance level of pathogenic bacteria increases and the control effect decreases
Moreover, there is currently a lack of medicaments that can simultaneously prevent and treat bacterial and fungal diseases on the market; when farmers prevent and treat these two diseases, they usually use two single agents to mix and use at will, which not only fails to achieve synergistic effect, but may produce antagonism effect, the control effect is reduced

Abstract

The invention provides a compound composition containing methanesulphonyl myclobutanil and carbamic acid ester bactericide and a preparation. The active ingredients of the compound composition comprise A and B, wherein A is methanesulphonyl myclobutanil, and B is an active bactericidal compound selected from carbamic acid ester bactericide propamocarb hydrochloride, diethofencarb, benthiavalicarb-isopropyl and iprovalicarb, wherein the chemical name of methanesulphonyl myclobutanil is 2-(p- fluorophenyl)-5-methylsulfonyl-1, 3, 4-oxadiazole. After additives or carriers are added, the compound composition can be prepared into such dosage forms as wettable powder, water dispersible granules, suspension, emulsion in water, granules and seed coating. The active ingredients A and B are compounded to have an obvious synergistic effect and can effectively prevent and treat various bacterial diseases and various fungal diseases, and the compound composition has the effects of strengthening the synergistic effect, expanding the disease prevention and treatment spectrum, alleviating the drug resistance and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition of mesycloconazole and other fungicides and a preparation thereof. Background technique [0002] Chemical agents are an important means to prevent and control bacterial and fungal diseases, and chemical control is still the main method at present. However, due to long-term use of the same chemical agent, the resistance level of pathogenic bacteria increases and the control effect decreases. Moreover, there is currently a lack of medicaments that can simultaneously prevent and treat bacterial and fungal diseases on the market; when farmers prevent and treat these two diseases, they usually use two single agents to mix and use at will, which not only fails to achieve synergistic effect, but may produce antagonism effect, but the control effect is reduced. Therefore, it is necessary to develop a compound composition with high efficiency and broad spectrum...
