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.
