Embodiment 1

[0019] Example 1. In the high-speed shear mixing kettle, add 6kg of cyhalofop-ethyl, 2kg of fenfentrazone, 8kg of emulsifier 8207, 0.5kg of thickener xanthan gum, 0.5kg of preservative sodium benzoate, make up to 100kg of water, and emulsify , homogenization, detection, and packaging to obtain the aqueous emulsion product of the compound herbicide of the present invention.

Embodiment 2

[0020] Example 2. In the high-speed shear mixing kettle, add 7kg of cyhalofop-ethyl, 1.8kg of fenfentrazone, 10kg of emulsifier 8207, 0.5kg of thickener xanthan gum, 0.5kg of preservative sodium benzoate, and add water to 100kg. Emulsification, homogenization, testing, and packaging can produce the aqueous emulsion product of the compound herbicide of the present invention.

Embodiment 3

Abstract

The invention relates to a complex herbicide for treating stems and leaves of rice, and belongs to the technical field of agricultural pesticides. The invention provides a complex herbicide for stems and leaves of a rice field, which not only can prevent and remove grassy weeds such as Leptochloa chinensis in the rice field and the like, but also can prevent and remove broadleaf weeds, and is safe to rice and has no influence on succeeding crops. The technical key point is that the complex herbicide comprises the following raw materials and auxiliary agents in part by weight: 5 to 8 parts of cyhalofop butyl, 1.6 to 2 parts of carfentrazone-ethyl, 5 to 15 parts of 8207 emulsifying agent, 0.5 part of xanthan gum, 0.5 part of sodium benzoate and 100 parts of water. The complex herbicide has obvious weeding effect, and is superior to two single agents; simultaneously, the complex herbicide is wide in weeding spectrum, can prevent and remove annual grassy weeds and broadleaf weeds, can prevent and remove the weeds in the whole growth period of the rice by once application, has no influence on the following crops, and is the ideal herbicide currently.

Description

Technical field: [0001] The invention relates to a field herbicide for crops, in particular to a compound herbicide for treating rice stems and leaves. technical background: [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 area of ​​moderate weed da...
