Q: Most of the local wheat fields in this year have not been closed. Now the wheat seedlings have exceeded 2 leaves and 1 heart. In order to prevent grass weeds, I want to use Maiji, I am worried that it is not effective for weeds; I want to use isoproturon , and I am worried that the low temperature will have a negative impact. I don't know if I can mix the Maiji and Isoprofen to achieve the best results. If so, what is the amount?
A: Maiji 15% acetylacetoate wettable powder, registered for use in wheat field to control grass weeds, for stem and leaf treatment agents, there is no sudden closure treatment effect, should be applied after the field grass weeds are basically out. Depending on the age of grass and weed resistance, the general grass is small, mainly low-resistant when looking at weeds such as aunt, can be 15 grams per gram of ketone 15% acetylene ester wettable powder; grass age or field When the weeds are mainly weeds with strong resistance such as valerian and hard grass, it is advisable to increase the dosage appropriately, and use 15% of acetylene oxalate wettable powder per acre. The mixture of clodinafop and its oxalic acid ester has good control effect at low temperature, and it is safe to the wheat seedlings. The above field can be used after the field weeds are basically out and the acetylene ester is applied. A compounding agent for oxalate.
Isoproturon has both soil closure and stem and leaf treatment effects. It should be applied when the weeds in the field are small, and it is also effective against weeds that are difficult to control with cloacae such as bluegrass (the occurrence of some wheatgrass in Taixing and other places) serious). Isoproturon can be mixed with clodinafop in production. The above-mentioned field can be considered to use 50% isoproturon WP 125-150 g per acre, 15% acetylene oxalate wettable powder, and 30 kg of water spray. Isoproturon will reduce the anti-freezing ability of wheat seedlings. If you choose to apply it in the near future, you should use high-quality isoproturon products, and pay attention to the application of cold-head warm head to ensure that the daily minimum temperature does not appear after 1 week after application. Weather below °C.
