WEEDS GROWING WHERE A HERBICIDE WAS USED 



In such a place, some weeds may emerge an inch or so and then die back. However, 

 if the weather has been dry and there is a question about how well the herbicide 

 has been absorbed by the weed seedlings, don't hesitate to use the rotary hoe. 

 You'll usually do much more good than harm. 



DELAYED APPLICATION OF PREEMERGENCE HERBICIDES 



Some farmers were in such a rush to plant this season that they didn't get a her- 

 bicide applied. Now, they wonder whether they should put it on several days later. 

 With some herbicides this can be done. Check the label for specifics. 



With late planting and dry weather, the need for herbicides is usually smaller. The 

 rotary hoe and cultivator may be enough to help give soybeans a head start on weeds -- 

 if the weather doesn't turn wet again. 



In the old days, some folks didn't think they had done their "just duty" unless they 

 cultivated corn four times, weeds or not. Today, there seem to be some similar 

 feelings about herbicides.
