Example

[0039] Implementation application example 1:

[0040] Test report on activity determination of weeds in corn field by mixed pair of mesotrione and fluroxypyr

[0041] Test purpose: To determine the herbicidal effects of mesotrione, fluroxypyr and their different combinations on Portulaca under potting conditions in a greenhouse, and to evaluate their combined effects, and to develop and develop the formulations of mixed agents Pesticide registration field efficacy trials provide scientific basis.

[0042] Test target: Portulaca oleracea (Portulaca oleracea L).

[0043] Test agents: Mesotrione (mesotrione) 94% original drug, fluroxypyr (fluroxypyr) 96% original drug, all provided by Shaanxi Welch Crop Protection Co., Ltd.

[0044] Pharmacy configuration:

[0045] Mesotrione solution: accurately weigh out 0.0325g of 94% mesotrione original drug, dissolve it with 0.2mL DMF, add 400mL of clear water containing 0.1% TWEEN80 emulsifier, stir evenly, and prepare mesotrione 120g ai / The ha sol...

Example Embodiment

[0063] Example 1 60% Mesotrione·Floperoxyacetic acid wettable powder

[0064] Mesotrione 10%, fluroxypyr 50%, lignosulfonate 8%, saponin powder 6%, white carbon black 10%, kaolin added to 100%, the mixture is jet pulverized to obtain 60 %Mesotrione·Chloropyroxyacetic acid wettable powder.

Abstract

The invention relates to a herbicidal composition containing mesotrione and fluroxypyr, the composition is mainly characterized in that: the herbicidal composition contains 1-60% of mesotrione, 1-60% of fluroxypyr 60%, auxiliary agent and other excipients, made into wettable powder, water dispersible granule, suspension concentrate, suspoemulsion, microemulsion, water emulsion. The herbicidal composition of the present invention is used for controlling broadleaf weeds, gramineous weeds and sedge weeds in corn fields and wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition of mesotrione and fluroxyrpyr for preventing and controlling common weeds in corn fields and wheat fields. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the best synergistic effect can be obtained from the pesticid...
