There is also interest in Lorox and Lasso as a preemergence , tank-mix combination. 

 The Lorox rate will need to be adjusted for soil type to give a maximum margin 

 between soybean tolerance and selective weed control. 



NEW DINITRO CLEARANCE 



Dow has announced that " Preemerge" (dinitro) has been cleared for directed post- 

 emergence use on seed soybeans. Dinitro previously had clearance only for use 

 on soybeans from the cracking stage- -as plants emerge- -until the first true leaves 

 form. Present clearance is for use from the time soybeans are 5 to 6 inches tall 

 until they bloom. 



The purpose of this restricted registration is to control some broadleaved weeds, 

 such as cocklebur and morningglory , which are tolerant to most preemergence 

 herbicides .
