May have sprayed some newly sprouted cucumber plants and 8" tall tomato plants by mistake. How soon would tender plants show symptoms so I'll know whether to replant? I understand it normally takes a week or more to see results but should very tender plants show signs sooner?
An herbicide such as Bio Advanced Brush Killer Plus Concentrate will generally cause visible yellowing or wilting on plants within about 7-10 days, and sooner in warmer weather. This label does indicated that visible results may take from 1-6 weeks (this should be on the short end for young plant). If desirable plants are accidentally sprayed, then you should rinse them with water as soon as possible.
We recommend watching the plants for at least a week, and if you see that plants in an area were damaged, you should not replant in that area for at least one month, and preferably for one year. Please refer to the product label for complete application instructions.
