Collapse ▲I would like to share several questions received at the Caldwell Extension Center this week, along with their respective answers, which I believe will be of interest to readers.
Q: How can I control fire ants without harming my chickens?
A: Fire ant baits are great for controlling fire ants. Typically, I recommend fire ant baits because they are inexpensive, effective, and easy to apply. However, baits and backyard chickens are not a good combination. Chickens or other backyard foul should not be allowed access to areas where fire ant baits have been applied.

If excluding poultry from the treatment area is not feasible, I recommend using Conserve SC. The active ingredient in Conserve SC is spinosad, a compound derived from a naturally occurring soil bacterium. This product is applied as a mound drench when treating fire ant colonies. Always read and follow the pesticide label instructions carefully.
Q: What can I use to control watershield in my pond?
A: Watershield, an emergent aquatic weed, is highly susceptible to aquatic formulations of 2,4-D. To minimize the risk of fish kills, treat only one-quarter of the pond at a time. Fish kills may occur due to oxygen depletion as decomposing vegetation consumes dissolved oxygen in the water.

Ensure you read and follow the label instructions for the specific 2,4-D formulation used. The label will list specific restrictions about fishing, swimming, livestock watering, and irrigation. Different formulations have varying restrictions.
Q: How can I control clover in my yard?
A: White clover is a common weed that thrives in closely mowed and under-fertilized lawns. To promote a healthy, vigorous turf that can outcompete clover, fertilize your lawn at recommended rates and mow at the appropriate height. For tall fescue lawns, maintain a mowing height of 3.5 to 4 inches and fertilize in February, September, and late October.
A soil test can identify and address underlying fertility issues that may contribute to the problem. We recommend conducting a soil test every three years.
If needed, herbicides containing the active ingredients fluroxypyr, triclopyr, or quinclorac are effective against white clover. Common trade names for these herbicides include Confront, Escalade 2, and Q4 Plus.

Always read and follow the label instructions for proper application and safety.
