Q. Why do my harvested potatoes have lots of little holes in them?
A. Round holes in potato tubers most likely are caused by insect larvae. Common insect suspects are wireworms and potato tuber worm. Holes in tubers from insect feeding damage will be more likely to become infested with storage rot organisms if held in storage for an extended period.
Q. When can I sign up my child to join a 4-H club?
A. The 4-H year starts Oct. 1, so that is the best time to get your child signed up. You can contact the Franklin County WSU Extension Office at 545-3511 for more information about joining 4-H, starting a club, and everything else you want to know about 4-H.
Q. My friend told me he had woolly apple aphid on his apple tree last year. What is the woolly apple aphid and what does it look like?
A. Woolly apple aphids are a pest of tree fruit that have a white cottonlike appearance. They are usually present in great numbers.
There are many predators, like ladybugs and lacewings, that can help control aphid populations. If the aphids become too numerous and your trees are small, apply insecticides directly to the insects, this will help to eliminate killing their predators.
Q. I've heard that fall is a good time to fertilize my lawn? Is this true and what type is best?
A. Early September and again in early November are the best times to fertilize your lawn. Use a balanced fertilizer with an NPK (nitrogen, phosphorus and potassium) ratio of 3:1:2 and apply it at a rate of 1 pound of nitrogen per 1,000 square feet. Fertilizing at this time of year encourages sideways growth or increased turf thickness instead of leaf blade growth upwards. A healthy dense lawn is a good defense against weeds and lawn diseases. Your November application should be applied after the last mowing but before the soil freezes. If you fertilize in the fall, you won't need to fertilize again until the beginning of May.
