Late Applications of PPO Herbicides<BR>The diphenyl ether herbicides (Cobra, Reflex, Ultra Blazer) applied at reproductive growth stages (R1, R3, R5) have no negative impact on developing soybean flowers and pods. Even with foliar injury as high as 55%, soybean plants are able to compensate for this injury and produce yields comparable to nontreated soybean plants. Applications made by growers as “rescue” applications late in the season do not lead to soybean yield loss. <BR>Source: Beam et al. 2018. Weed Technology 32:444-447<BR>
