Abstract
The present invention relates to a kind of raising herbicides to the method for wheat weeds control effect.The method includes：Wheat seed is handled first with mefenpyrdiethyl, then is prevented using herbicide；Wherein, the processing is coating, dresses seed or soak seed.Compared with the existing technology, the present invention can reduce herbicide dosage, improve safety of the herbicide to control of weeds effect, raising herbicide to wheat.
Description
Technical field
The present invention relates to control of weeds technical fields, and in particular, to a kind of raising herbicide, which prevents wheat weeds, imitates
The method of fruit.
Background technology
It is reported that China's wheatland crop smothering occurring area accounts for 55% of cultivated area or more, seriously endangers area and account for 28%, put down
Equal production loss is expanded rapidly up to 15%, wherein the wheatlands malignant weed such as Triticum tauschii, in recent years occurring area, causes wheat serious
The underproduction is even had no harvest；Meanwhile with the continuous improvement of China's labor cost, using the harm of herbicide control wheat weeds
As the required measure of Wheat Production.But herbicide, as the maximum a kind of chemical pesticide of usage amount, long-term a large amount of uses are made
At serious environmental pollution and ecological disruption, therefore, control effect of the herbicide to weeds how is improved, reduces herbicide and use
Amount is to need the major issue solved in production.
Mefenpyrdiethyl is a kind of insecticides adjuvant, and existing literature reports that mefenpyrdiethyl can improve wheat to herbicide
Drug resistance and the weeds such as wild oat are not influenced, therefore be added in herbicide formulations, and be sprayed on crop cauline leaf, to carry
High herbicidal agent makes have serious poisoning oxazoles diclofop-methyl, mesosulfuron etc. to wheat originally to the selectivity of wheat and weeds
Herbicide can be used for cornfield herbicidal after adding mefenpyrdiethyl.
However, applicant be by the study found that although mefenpyrdiethyl can improve drug resistance of the wheat to herbicide,
Drug resistance of the weeds such as Triticum tauschii to herbicide is improved simultaneously, so that herbicide is reduced such Weed-control effect, causes in production
Herbicide dosage is significantly increased.
