| Abstract: | When the 2,4 - D dimethylamine salt 86 % AS 1 was sprayed for 30 d , its control effect reached 72. 04 % ,94. 92 % ,85.22 % and 95.92 % respectively for Galium aparine L. , Euphorbia helioscopia L , Polygonum convolvulus L and Chenopodium album L. and its control effect were 76. 61% ,97.73 % ,97.77 % and 98. 54 % after 50d. When the drugs were used for 50 d , the control effects of 2,4 - D dimethyla mine salt 86 % AS on the fresh weight of Galium aparine L. , Euphorbia helioscopia L. ,Polygonum convolvulus L. and Chenopodium album L were 72.76 % ,98. 73 % ,97.49 % and 99. 34 % respectively, which are higher that in 2,4 - D butylate 72 % EC with the applied concentration of 540. 0g a. i. / hm2 but no significant differences among the five treatments. The yield increasing rate of its reached above 8 %. It did not affect spring wheat growth and it had the popularization value in the field production. |
