Abstract
In order to clarify the occurrence regularity of herbicide phytotoxicity and select the suitable herbicides in spring rape field,six common herbicides were chosen to study the influences of phytotoxicity occurrence on the growth of spring rape.The results showed that benazolin easily caused phytotoxicity when used to control weeds in spring rape field.It should be applied carefully,not over the maximum dosage(1 950mL/ha).Trifluralin,acetochlor and ethmmetsulfuron created serious phytotoxicity and had influence on plant height and flower numbers of spring rape after applying the dosage of two-fold high amount(6 000mL/ha,2 010mL/ha,300g/ha,respectively).The inhibition ratios of flower number proportion were 56.25%,43.19%,13.06%,and the inhibition ratios of plant height were 15.57%,14.10%,10.53% after applying the three herbicides.The yields severely reduced,respectively down 47.81%,44.16%,18.61%.Thus,they should not be applied over the maximum dosage(3 000mL/ha,1 005mL/ha,150g/ha).There was no obvious phytotoxicity and no effect on crop growth,and yield was identical with the control after applying clopyralid and quizalofop with dosage of high amount and two-fold high amount.The two herbicides were recommended to use in the spring rape field to control weeds.
