Embodiment 1

[0029] A herbicidal composition is composed of trifloxysulfuron-methyl, diethylhexanoate and auxiliary materials. The weight ratio of trifloxysulfuron-methyl to diamine fresh fat is 10:1, the weight of the active component is 90% of the total weight of the composition, and the auxiliary materials are fillers, dispersants and dispersants with a weight of 1:1:1:1. In agent, wetting agent, synergist, described filler is diatomaceous earth; Described dispersant is sodium naphthalenesulfonate formaldehyde condensate (dispersant NNO); Described wetting agent is sodium lauryl sulfate; The synergist fatty alcohol polyoxyethylene ether (JFC). The above-mentioned several ingredients are fully mixed, and a wettable powder is prepared by a conventional production method. Accurately weigh 50 g of the powder prepared above, and fully dissolve it in 15 kg of water containing 10 ml of organic silicon.

[0030] In the middle and late May, when the leaves of cotton are 5-6, take the above-men...

Embodiment 2

[0032] The method is the same as in Example 1, but the herbicidal composition used is a single dose of trifluxuron-methyl or a single dose of diethylhexanoate, and other parameters are the same as in Example 1.

[0033] Examples of efficacy identification

[0034]Trifluxysulfuron-methyl single agent, amine fresh fat single agent and their different combinations were tested for community control. The set dose of trifluxysulfuron-methyl was 16g-26g / mu with a gradient of 2g; the set dose of amine fresh fat It is 0.5g-3.5g / mu, and the gradient is 0.5g; According to the trifluxysulfuron-methyl single-dose test result, in the combination of trifluxysulfuron-methyl+amine fresh fat, the reference dose of trifluxysulfuron-methyl is set as 20g / mu, amine fresh fat from 0.5g / mu-5.0g / mu, the gradient of amine fresh fat is 0.5g, calculate the control effect of weeds, the specific calculation formula of control effect is:

[0035]

[0036] See Table 1 for specific prevention effects:

Embodiment 3

[0043] The method is the same as in Example 1, but the herbicidal composition used is thifensulfuron-methyl (sulfonylurea) and amine fresh fat in a weight ratio of 10:1, and other parameters are the same as in Example 1.

Abstract

The invention provides a trifloxysulfuron and diethyl aminoethyl hexanoate-containing weeding composition and application thereof. The weeding composition contains trifloxysulfuron and diethyl aminoethyl hexanoate; the weight ratio of the trifloxysulfuron to the diethyl aminoethyl hexanoate is (20: 1) to (2: 1), preferably (10: 1) to (4: 1); and the weight of active components is 5 to 95 percent of the total weight of the composition, preferably 10 to 90 percent. The weeding composition provided by the invention is good in weeding effect and wide in herbicide controlling spectrum, and the control effect on weeds in a cotton field can be enhanced to a large extent.

Description

technical field [0001] The invention relates to the technical field of pesticide pharmacy, in particular to a herbicidal composition containing triflusulfuron-methyl and diethylhexanoate and its application. At the same time, the present invention relates to an application method for controlling difficult-to-remove weeds and resistant weeds in cotton fields, sugarcane fields, orchards, tea gardens, mulberry gardens, sisal hemp gardens and rubber gardens. Background technique [0002] Cyperus cyperus (Three-edge grass) is a perennial weed of Cyperaceae. With long creeping rhizomes and black hard ovate tubers. Stems scattered, erect, sharply triangular. Leaves basal, shorter than stem, shiny; base of leaf sheath brown. Cyperus cyperi (trigonium) reproduces by tubers and seeds, and is born in farmland with moist soil, roadside or wasteland. Some cotton fields are severely damaged, and it is a very difficult to control cotton field weed. When it occurs seriously, it can damag...
