Wilt of Vining Crops

Posted by John Fulton -

With the growing season entering the home stretch for vining crops such as squash, pumpkins, cucumbers, and melons, there are few things worse than having your vines wilt suddenly. I've noticed the population of the striped cucumber beetles have exploded in the past few weeks. These beetles can be green, black and yellow striped, or black and yellow spotted. The importance of the beetles is not that they eat small holes in the leaves, but that the beetles can transmit a bacterial wilt to the plants as they eat. The first thing you see is you have a plant that suddenly wilts on various runners, or the entire plant. The best means of controlling this disease is a good beetle control program. Current homeowner recommendations would include these products with the days to harvest restrictions in parenthesis: carbaryl (0), bifenthrin (3 days), or rotenone (1 day).
