Problems solved by technology

Penoxsulam is highly effective against barnyard grass, and also has good control effect on Cyperaceae and broad-leaved weeds, but it is not effective against Qianjinzi
This product has poor selectivity to wet-inserted rice when it is applied alone, but it has excellent selectivity to in-line rice when it is used together with chlorpyrifos

Embodiment 1

[0030] Embodiment 1: 30% penoxsulam, pyrazosulfuron-methyl and pretilachlor dispersible oil suspension concentrate (penoxsulam: pyrazosulfuron-methyl: pretilachlor=1.5:0.75:27.75=2:1 :37)

[0031] Take 1.5kg of penoxsulam, 0.75kg of pyrazosulfuron-methyl, 27.75kg of pretilachlor, 6kg of 500#, 8kg of EL-20, 2kg of magnesium aluminum silicate, and methylated vegetable oil to make up to 100kg. The dispersible oil suspension is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Embodiment 2

[0032] Example 2: 40% penoxsulam · pyrazosulfuron-methyl · pretilachlor wettable powder (penoxsulam: pyrazosulfuron-methyl: pretilachlor=3:2:35)

[0033] Take 3kg of penoxsulam, 2kg of pyrazosulfuron-methyl, 35kg of pretilachlor, 4kg of dispersant NNO, 3kg of wetting agent K12, 4kg of white carbon black, and light calcium carbonate to make up to 100kg. Wettable powder is obtained through thorough mixing, jet milling and mixing.

Embodiment 3

[0034] Example 3: 28% penoxsulam · pyrazosulfuron · pretilachlor floating granule (penoxsulam: pyrazosulfuron: pretilachlor=2:1:25)

[0035] Take 2kg of penoxsulam, 1kg of pyrazosulfuron-methyl, 25kg of pretilachlor, 7kg of D-425, 5kg of EFW, 5kg of ammonium sulfate, 2kg of polyethylene glycol, and hollow glass microspheres to make up 100%. Crushing, mixing, granulating, drying and sieving to obtain floating granules.

[0036] 2. Determination of indoor biological activity:

[0037]Under greenhouse conditions, pot experiments were used to study the herbicidal effect of penoxsulam, pyrazosulfuron-methyl and pretilachlor, and Sun Yunpei’s co-toxicity coefficient method was used to evaluate the combined effect of the three in different proportions. Provide a scientific basis for the rational mixing of penoxsulam, pyrazosulfuron-methyl and pretilachlor.

Abstract

The invention discloses a comprehensive weeding composition of a paddy field. The weeding composition contains active ingredients such as penoxsulam, pyrazosulfuron-ethyl and pretilachlor, wherein the mass ratio of penoxsulam to pyrazosulfuron-ethyl to pretilachlor is (1.2-3): (0.5-2): (20-35). The comprehensive weeding composition can be used for the pre-emergence treatment, and also can be used for the post-emergence treatment; moreover, a good effect for removing and controlling the gramineae weeds, broadleaf weeds and cyperaceae weeds is good. The weeding composition is safe to the paddy rice, wide in herbicide controlling spectrum, small in consumption amount and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a comprehensive herbicide composition for paddy fields. Background technique [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population, including almost all of East and Southeast Asia, eat rice. Production is on every continent except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. my country's rice sowing area accounts for 1 / 4 of the country's food crops, about 35 million hectares per year, while the output accounts for more than half. Regardless of the planting area and output, it ranks first in my country's food crops. There have always been a large number of weeds in the paddy fields of all rice-growing areas in my country. The a...
