Control Rice Insects with Effective Seed Treatment
Rice insect pests, including rice water weevil, stem borer, sugarcane borer and Mexican rice borer, are difficult to control with traditional methods. Their larvae feed inside the plant where conventional insecticides can’t reach. Once larval feeding begins, it’s usually too late to do much about it other than drain the field.
Ray Stoesser, a rice farmer near Dayton, Texas, knows the challenges of rice insects all too well. A rice grower since 1966, Stoesser has been successful with more good years than bad. But the drought of 2011 was a bad year. Because of the drought, he wasn’t able to get water over the rice the way he’d have liked to. And that year the heat allowed insects to get a head start on the crop.
“In a lot of our fields, insects sucked the juice right out of the plants and killed them,” said Stoesser. “I didn’t want a repeat of that in 2012, so I attended a lot of meetings and read about better insect control products. Presentations in my region from DuPont convinced me to learn more about Dermacor® X-100 seed treatment. I found out that Dr. M.O. Way, an entomologist at Texas A&M who I highly respect, recommended the product based on his research, so I decided to treat all of our 4,500 acres of rice with Dermacor®. It gave us long-lasting protection from stem borer, rice water weevil and late-season protection against Mexican rice borer and sugarcane borer on the ratoon crop. We didn’t have to spray any other insecticides except for Karate to control stinkbugs at heading. Even though 2012 was another hot year, we had excellent insect control and a good crop. Much better than 2011.”
Until recently, rice growers who wanted to control weevils and borers were limited to trying to time a foliar insecticide application to the arrival of egg-laying adults, or planting rice early to avoid peak egg-laying periods. Both strategies are prone to disappointing results, either due to missing the peak flights of adults or planting so early that cool temperatures reduce rice emergence and yield.
These factors have led to a growing trend of using preventive insect control from the start. DuPont™ Dermacor® X-100 seed treatment is one such product that now has a federal label for dry-seeded rice use in most rice-growing states across the South.
To meet the needs of rice growers in Louisiana, Dermacor® X-100 received a section 24(c) special local needs label in 2012 for use as a seed treatment on flooded rice fields in Louisiana that aren’t used for aquaculture, such as fish or crawfish production.
“Dermacor® X-100 seed treatment fills a critical need by helping rice growers maximize the yield potential of their crop,” said Suniti Moudgil, portfolio manager, DuPont Crop Protection. “When used according to the label, Dermacor® X-100 provides early control of damaging insects like rice water weevil, resulting in a stronger root mass and a healthier crop.
“This highly effective control continues through stand establishment and heading for long-lasting protection against later-season pests like stem borers. And the excellent environmental profile Dermacor® X-100 offers makes it a logical addition to crop protection programs for rice growers who are seeking a more-sustainable crop protection program for their farming operation.”
Stoesser says he’s convinced Dermacor® X-100 seed treatment is the best rice insect control solution for him. “We plant RiceTec hybrid seed at the recommended lower rate of 22 to 23 pounds of seed per acre. With less seed per acre, we need to make sure that every seed survives.”
