Embodiment 1、235

[0026] Embodiment 1, 23.5% emulsifiable concentrate:

[0027]

[0028] Preparation method: Put the above-mentioned raw materials into the reaction kettle according to the ratio, stir and mix, then settle, and get the product after sampling and analysis are qualified.

Embodiment 2、315

[0029] Embodiment 2, 31.5% suspending agent

[0030]

[0031]

[0032] Preparation method: Mix all components according to the ratio and feed, stir for 20 minutes and mix well. Put it into the colloid mill for initial sanding, turn on the air source to control the temperature, and then enter the sand mill for sanding for 2.5-3.0 hours, and then enter high-speed homogeneous shearing and stirring for 10 minutes to obtain a uniform liquid.

Abstract

The invention discloses a weeding composition containing profoxydim and fluroxypyr. The effective components of the weeding composition are profoxydim and fluroxypyr, wherein a mass ratio of the profoxydim to the fluroxypyr is (2.5-20): (21-50). The weeding composition can prevent and kill gramineous weeds and broadleaf weeds at the same time through one-shot application, has the effects of expanding a weed control spectrum and enhancing effect, is reduced in dosage through compounding and high in safety, reduces application frequency, lowers application cost, and can also achieve the effectsof controlling weed population change, reducing pesticide resistance of weeds, maintaining agricultural ecological balance and protecting the environment; and therefore, the compounding of profoxydimand fluroxypyr is worth popularizing.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicidal composition of cycloclotrione and fluroxypyr. Background technique [0002] Cyclotrione is an ACCase inhibitor. After foliar application, it is quickly absorbed and transferred by the plant. It transfers to the growth point in the phloem and inhibits the growth of new shoots. The weeds will first lose their chlorosis, then change color and die, usually 2-3 weeks completely dead inside. It is mainly used to control gramineous weeds in rice fields such as barnyardgrass, blue horsegrass, crabgrass, daughter of a thousand golds, foxtails, and tulips. It is safe for direct-seeding rice and transplanting rice; but for broad-leaved and sedge weeds The control effect is not ideal. [0003] Fluroxypyr is a pyridyloxyacetic acid herbicide with systemic conduction effect. It is used after seedlings and is quickly absorbed by plants after treatment, ca...
