Application of propargyl oxadiazone in crops other than rice
1 Application of propargyl oxadiazone on potato
Gong Xiangyu et al. used 80% propargyl oxadiazone WP to conduct a pre-emergence one-time weed control experiment in potato fields, and investigated the efficacy of propargyl oxadiazone. The results showed that 30 days after potato emergence, the plant control effect of propargyl oxadiazone on weeds was 62.0%-98.6%, the inhibition rate on the fresh weight of weeds was 68.8%-98.5%, and the potato yield was increased by more than 6%. All treatments are safe to potatoes and have no phytotoxicity.
2 Application of propargyl oxadiazone in corn
The recommended dose of 80% propargyl oxadiazone wettable powder on corn is 8-12 g/mu. It is best to compound with acetochlor for soil sealing in application. The control effect is above 90%. It is safe for corn and has no phytotoxicity.
3 Application of propargyl oxadiazone in soybean
Gong Xiangyu et al. selected 80% propargyl oxadiazone wettable powder to control weeds in spring soybean field once after soybean sowing and preemergence application. 80% propargyl oxadiazone wettable powder can effectively control weeds such as barnyardgrass, cabbage, radish, cabbage, foxtail, lettuce, spinach and other weeds in soybean fields. Gram a.i./mu mixed with acetochlor 900 g/liter EC 45 g a.i./mu) has the best effect, and the control effect reaches 90%. Treatment 3 (propargyl oxadiazone 80% wettable powder 9.6 g a.i./mu) Next, treatment 1 (propargyl oxadiazone 80% wettable powder 4.8 g a.i./mu) was the lowest, but the control effect also reached more than 80%. It is safe and harmless to the growth of soybeans, and is safe to subsequent crops.
