Spider mites – Unlike most other living things, spider mites love dry weather. So, naturally, they can be found on all kinds of plants this summer. Look for the telltale white speckled leaves, or put a white sheet of paper underneath a leaf, shake the leaf and look for movement. Try strong blasts of water from the hose on leaves, including undersides, to try to dislodge them. You can also use horticultural oil, insecticidal soap or miticides; be sure to avoid the hottest parts of the day for that job and do it in the morning or evening, extension agent Rebecca McMahon says. Plant injury can result if you apply any miticide, insecticide or fungicide when the air temperature is above 85 degrees, Raymond Cloyd, K-State Research and Extension entomologist, says.
“Mites aren’t an insect. They’re in a whole different family, along with spiders, ticks and scorpions,” Cloyd says. “Spraying an infested plant with an insecticide simply eliminates the mites’ natural enemies. Applications of carbaryl (Sevin, Adios, and Slam) have paved the way for some notably severe spider mite outbreaks.”
Fall gardening, anyone? – If you want to start a fall garden now, start as much as you can from seed indoors and put transplants out in mid- to late August, Rebecca says. This works particularly well for lettuce, which transplants well, she says. You can also wait until late August and early September to plant, because these kinds of plants are very cold-tolerant.
Emerald ash borer – You may have heard that the dreaded emerald ash borer has been found in Kansas City, and it also is expanding in southern Missouri. Keeping trees healthy and buying firewood that is only from our area are two things we can do to delay as long as possible its incursion here. Extension agent Bob Neier said he learned that imidacloprid drenches on or before April 1 each year help prevent the insect from entering ash. The borer has killed more than 50 million ash trees in the United States in the past 10 years.
