Problems solved by technology

[0010] At present, there are few studies on the compounding of different types of pesticides such as insecticides and fungicides, and most of the existing studies are still at the level of tank mixing or simple combination. There is no synergy in the prevention

specific Embodiment approach

[0167] The present invention will be further described below in conjunction with embodiment:

Embodiment 125

[0169] Example 1 25% pyraclostrobin + 25% sulfoxaflor wettable powder

[0170] pyraclostrobin 25% Sulfoxaflor 25% Dispersongen® 1494 (From Clariant) 10% Kaolin Top up to 100%

[0171] The active ingredients, various additives and fillers are mixed according to the proportion of the formula, and after being pulverized by an ultrafine pulverizer, 25% pyraclostrobin + 25% sulfoxaflor wettable powder can be obtained.

Embodiment 2

[0172] Example 2 12.5% ​​pyraclostrobin + 25% sulfoxaflor suspension

[0173] pyraclostrobin 12.5% Sulfoxaflor 25% Sodium methylnaphthalenesulfonate formaldehyde condensate 5% Arkopal® N 130 (from Clariant) 5% xanthan gum 0.3% Glycerol 5% Defoamer 0.6% water Top up to 100%

[0174] Mix the active components, dispersant, wetting agent, water and other components according to the proportion of the formula, and grind and / or high-speed shearing to control the particle size below 5 μm to obtain 12.5% ​​pyraclostrobin + 25 % Sulfoxaflor suspension concentrate.

Abstract

The invention provides a crop protecting agent. The crop protecting agent comprises pyraclostrobin and sulfoxaflor in a weight ratio of 50:1 to 1:50. The prevention or control effect of the crop protecting agent on fungi and / or pests is not simple superposition of activity of components; the crop protecting agent has more obvious synergistic effect than an existing single preparation in addition to the remarkable control effect on the fungi and / or the pests. The crop protecting agent provides an effective prevention or control method for the conditions that the fungi and / or the pests are easily caused at the same time or already have or are likely to have resistance to currently known products.

Description

technical field [0001] The invention relates to a crop protection agent, in particular to a crop protection agent capable of effectively controlling fungi and / or pests simultaneously. Background technique [0002] With regard to pesticide activity, especially for crop protection, one of the central problems of research carried out in this technical field is the improvement of performance, especially with regard to biological activity and the maintenance of this activity over a certain period of time. [0003] Synergistic control of pests and diseases is a more effective method of control or prevention where fungi and / or pests are prone to mixed occurrence or have developed resistance or are at risk of developing resistance to currently known products. This results in improved growth characteristics of the plants, higher control of fungal infestation and / or pest infestation, and better crop cultivation.
