JimAus - 9/28/2010 15:56 Would Cyanazine (Bladex ) be better than Simazine? or safer? I was looking at using 2kg/ha (2lb/ac ) of Simazine ( loam soil ). Martin, I will be looking to plant chickpeas after the Corn, or if it is too wet (like this year) it will go back to corn. Our average ranfall for spring/summer is 7". Jim, Simazine is safer on corn than Bladex (cyanazine), although cyanazine has been banned in USA for over a decade, so my memory may not be perfect on this (we sometimes worried about Bladex dinking up the corn, but we've never worried about simazine -- always looks just fine, even on high-pH). Both chemistries have good activity on broadleaf weeds, but weaker on summer grasses. I wouldn't consider either of them very solid on summer annual grasses, but in a dry climate they might be adequate to good. For instance, Bladex was almost always tankmixed with atrazine to gain the synergy and improve control. 2 lbs/a of simazine (Princep) sounds like a lot. Remember that it has more soil activity than atrazine, so you can't compare rates of the two. Three-quarters of a pound of simazine probably provides more soil activity than a full lb of atrazine (although the simazine has less burndown capability). Martin, Chickpeas are very tolerant of pre-plant simazine. best regards,
