Synergistic interaction compound containing fluorophenyl ether amide and benthiavalicarb

Abstract

The invention relates to a synergistic interaction compound. Active ingredients of the synergistic interaction compound include fluorophenyl ether amide and benthiavalicarb, wherein the weight ratio of fluorophenyl ether amide to benthiavalicarb is (1:20)-(30:1), preferably (1:5)-(10:1). The synergistic interaction compound provided by the invention can be prepared into any preparation suitable for agricultural production and is especially suitable for preventing and controlling oomycetes diseases, such as downy mildew, powdery mildew and epidemic diseases. The synergistic interaction compound provided by the invention has excellent preventing and controlling effect, low cost, excellent lasting effect and fast-acting property.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a synergistic bactericidal composition. The active ingredients of the synergistic composition include fluphenamide and benthiazil, and are especially suitable for preventing and treating various oomycete diseases. Background technique [0002] Cucumber downy mildew is a plant disease caused by the flagellate subphylum Pseudoperonospermum cuba. Leaves develop from base to upper lobe. In the early stage of the disease, light yellow sub-circular to polygonal lesions are formed on the leaves, which are prone to be complicated by angular spot. When the air is humid, a frosty mold layer is formed on the back of the leaves, and sometimes it can spread to the leaves. In the later stage, the disease spots are withered and contiguous, and they are yellowish-brown. In severe cases, all the outer leaves are yellow and dead, similar to Verticillium wilt. Downy mildew overwinters as oos...

Problems solved by technology

Benthiopyram has a good inhibitory effect on the formation of oomycete sporangia and the germination of spores, but has no effect on the release of zoospores and the movement of zoospores. The results of field efficacy tests show that benthiazil can To control potato infestation resistant to benzamide fungicides and melon downy mildew resistant to methoxyacrylates, but the use of benthiazil alone is costly and has the risk of resistance

[0006] For a long time, the long-term and large-scale use of single pesticide active ingredient preparations has led to the continuous increase in the resistance of pathogenic bacteria, and the development cost of new pesticides has been further improved with the further improvement of environmental protection requirements, and the development cycle is relatively longer and the cost is higher. Therefore, how to develop old products? Potential promotion value, made in-depth research, on this basis, the inventor of the present application unexpectedly discovered through a large number of experiments that after compounding flufenamide and benthiazil, it can affect various crops within a certain range. The prevention and control of the disease shows an unexpected synergistic effect. After further research, the present invention has been completed. At present, there is no relevant report on the compounding of fluphenamide and benthiazil
