Problems solved by technology

The herbicidal effect of Tolpyralate is higher than that of mesotrione, fenflumezone or tembotrione. The disadvantage is that the control effect on some broad-leaved weeds is not ideal, and it is ineffective against Cyperaceae weeds
Arazine can promote plant growth at low concentrations, stimulate the growth of young shoots and roots, increase leaf area, thicken stems, etc. Although high doses can control some perennial weeds, there are still some weeds that are not effective Control, and will have a strong inhibitory effect on crops
[0015] Through searching, it is found that Tolpyralate is an excellent tank mixing partner with the commonly used herbicides glyphosate, glufosinate and dicamba; there are also patent documents disclosing herbicidal compositions containing Tolpyralate, chlorpyrazosulfuron-methyl or atrazine For example, the patent CN200980149775.

Example Embodiment

[0057] Formulation Example 1: 50% Tolpyralate·Chlorpyrazosulfuron·Atrazine WP

[0058]

[0059] After the above-mentioned raw materials are uniformly mixed according to the formula ratio, the conventional wettable powder preparation method, that is, pre-mixing, jet pulverization, and post-mixing is used to obtain 50% Tolpyralate·Chlorpyrimesulfuron·Atrazine wettable powder.

Example Embodiment

[0060] Formulation Example 2: 79% Tolpyralate·Chlorpyrazosulfuron·Atrazine WP

[0061]

[0062]

[0063] After the above-mentioned raw materials are uniformly mixed according to the formula ratio, the wettable powder is prepared by the conventional method of pre-mixing, jet pulverization, and post-mixing to obtain 79% Tolpyralate·Chlorpyrisulfuron·Atrazine wettable powder.

[0064] Formulation Example 3: 62.5% Tolpyralate·Chlorpyrazosulfuron·Atmazine WP

[0065]

[0066] After the above-mentioned raw materials are uniformly mixed according to the formula ratio, the wettable powder is prepared by the conventional method of pre-mixing, jet pulverization, and post-mixing, to obtain 62.5% Tolpyralate·Chlorpyrisulfuron·Atmazine wettable powder.

[0067] Formulation Example 4: 40% Tolpyralate·Chlorpyrisulfuron·Atmazine WP

[0068]

[0069] After the above-mentioned raw materials are uniformly mixed according to the formula ratio, the conventional wettable powder preparation method, namely pre...

Example Embodiment

[0070] Formulation Example 5: 32.5% Tolpyralate·Chlorpyrazosulfuron·Atrazine Water Dispersible Granules

[0071]

[0072] After mixing the above-mentioned raw materials uniformly according to the formula ratio, the conventional method of preparing water-dispersible granules, namely pre-mixing, jet pulverization, post-mixing, water-added kneading, granulation, and sieving, yields 24% Tolpyralate·Chlorpyrisulfuron· Atrazine water dispersible granules.

Abstract

The present invention relates to a cornfield herbicide composition, the composition is composed of Tolpyralate, chlorpyrazosulfuron-methyl and atrazine or atrazine selected from triazine herbicides, the three active ingredients in the composition are Weight ratio (0.75‑12): (0.5‑8): (22.5‑480) within the scope of compounding shows excellent synergistic effect, the composition after mixing significantly improved the herbicidal effect, reducing the The dosage used reduces the adverse impact of pesticides on the ecological environment while reducing the cost of pesticides for farmers. This herbicide composition not only has an obvious weeding effect, but also is safe for corn and has no effect on subsequent crops, meeting the safety requirements of pesticide formulations. .

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicide composition containing Tolpyralate, which is used for controlling weeds in cornfields. 【Background technique】 [0002] Corn is one of the main food crops in my country. Weeds in corn fields are very serious, and there are many varieties of corn in my country, and the varieties planted in different regions are quite different. The safety of herbicides on different corn varieties has attracted increasing attention. At present, the herbicides used in post-emergence domestic corn fields mainly include: nicosulfuron, rimsulfuron, mesotrione, dicamba, thiasulfuron, bromoxynil, etc., and the mixed preparations include nicosulfuron and atraz Zin, dicamba and atrazine, nicosulfuron and metrizone, etc., but these herbicides are still not completely effective in controlling some malignant weeds, such as Cyperus cyperi, Commelina, and Abutilon. Studies have show...
