| Abstract: | 70% Flucarbazone WDG is a new herbicide for controlling weeds in spring wheat fields. Field trial was conducted in order to clarify its effect of weed controlling and safety to the spring wheat. The results showed that 70% Flucarbazone WDG control could effectively several kinds of grassy weed, its normal dosage was 45 - 60 ml/hm2in the term of 3 ~ 5 leaves and broadleaf at 1 - 8 leaves with 300 kg water. Applied 70% Flucarbazone WDG was safety to the spring wheat variety Qing - chun 38 and the yield of wheat were in- creased by 4.02% -5.06% than CK. |
