| Precautions | Propylpropyl ether activity play a relatively slow, 10 days after the onset of symptoms weakened drug symptoms, weeds after 20 days showed significant injury symptoms. The drug is safer to the Brassica napus. When the amount of the product is more than 900ml / hm2, the rapeseed has a certain inhibitory effect on the rapeseed growth, but it can quickly return to normal without obvious adverse effect on the yield. Greenhouse tests showed that the safety of crop seedlings in the range of 375-4,500 ml / hm2 of commodity is: Cotton & gt; Rape & gt; Wheat & gt; Soy & gt; Corn & gt; 10% Propyl Ester Ether is safe for rape with more than 4 leaves.
