Wet Weather Concerns (Prostko)<\/a><\/h3>\n\n\n\n

Over the past few days, many locations in south Georgia have received significant rainfall (Figure 1).\u00a0<\/p>\n\n\n\n

A few things to think about:<\/p>\n\n\n\n

1) Keep an eye on rain-free periods for postemergence (POST) herbicides.  For my crops, these are listed in the UGA Pest Control Handbook (Remarks and Precautions).  If I am missing one, please let me know.<\/p>\n\n\n\n

2) Cool, cloudy, wet weather has a significant influence on the cuticles of plant leaves (i.e. makes them thinner).  Thus, pesticides applied during this type of weather can cause more crop injury symptoms.<\/p>\n\n\n\n

3) Residual weed control will likely be compromised (shorter than normal).  Applications of additional residual herbicides should be strongly considered  (Anthem Flex, Dual Magnum, Outlook, Warrant, Zidua).<\/p>\n\n\n\n

4) It is also very likely that some growers will not be able to get back into their fields on a timely basis to make POST herbicide applications.  There are no POST herbicides, in any of my crops, that can consistently control a pigweed that is bigger than about 3-4″ tall.  Thus, applying herbicides to very large weeds (revenge spraying) is a waste of time and money!<\/em><\/strong>  Hand-weeding, mechanical cultivation, non-selective applicators, and mowing are the only effective options for large weeds.<\/p>\n\n\n\n

5) Since applications of POST herbicides will be delayed, experience tells me that many growers will want to apply broadleaf and grass herbicides together.  Tank-mixing grass herbicides with broadleaf herbicides (Cadre + Select or 2,4-DB + Select), is labeled\/legal but will often result in reduced grass control (~10-20%).  Growers can increase the rate of the grass herbicide (within label) but I prefer a split application (grass herbicide first then broadleaf herbicide ~3-5 days later).<\/p>\n","protected":false},"excerpt":{"rendered":"
