| Abstract: | MCPA -sodium 56% SP 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 result showed that MCPA - sodium 56% SP control could effectively several kinds of broadleaf weeds, its normal dosage was 2250 - 3750g/hmEin the term of 3 - 5 leaves and hroadleaf at 2 - 8 leaves with 300kg water. Applied MCPA - sodium 56% SP was safety to the spring wheat variety Gaoyuan 438 and the yield of wheat were increased by 9.47% - 10. 24% than CK. |
