Registration of acequinocyl gives blueberry growers a fast-acting miticide with a different mode of action making it a good rotation tool for resistance management. The United States is the world’s largest commercial producer of blueberries. Blueberries are commercially produced in 38 states with 10 states accounting for more than 98 percent of the U.S. production. […]

The registration of the insecticide acetamiprid through IR-4 Project adds an important integrated management tool for control of papaya mealybug. Even though the United States imports most of its fresh papaya from Mexico, the tropical fruit is grown domestically in Hawaii, Florida, Texas, California and Puerto Rico. Hawaii is the largest producer with over 10 […]

Coffee growers work with IR-4 Project researchers and university cooperative extension agents to develop effective integrated control programs to limit damage from coffee berry borer. Only the European Union imports more coffee beans than the United States. About 90 percent of the coffee consumed in the United States is imported. According to USDA, most of […]

Researchers are conducting trials through IR-4 Project to determine the weed control effectiveness of clomazone as a post-transplant application. Clomazone has become an important weed control tool for specialty crop growers. This pre-emergent herbicide provides effective control of many annual grasses and common broadleaf weeds. Through the IR-4 Project, researchers are now studying whether this […]

Cilantro and dill growers and researchers work together to expand registration of clomazone through IR-4 Project. Growing multiple vegetable crops can be a blessing and a curse. Ratto Bros. Inc. in Modesto, Calif., produces 38 different crops, primarily leafy greens and herbs. “We grow a broad spectrum of crops,” said Brandon Narron, ranch manager at […]

Resistant varieties and additional fungicides can assist growers in protecting their basil crops from downy mildew infection.

IR-4 Project realized the importance of registering flonicamid for use on safflower to control lygus bugs to prevent damage to other major high value crops. When Beau Howard, a safflower grower and agronomist in California, submitted the project clearance request through IR-4 Project for flonicamid to control lygus bugs (Lygus hersperus) on safflower, he knew […]

Registration of the herbicide clomazone through the IR-4 Project offers asparagus growers another weed management tool. Even as the consumption of asparagus by US consumers has steadily increased, the amount of domestic production continues to decline. US per capita consumption of asparagus increased from 0.8 pounds in 1980 to nearly 1.6 pounds in 2017. According […]

IR-4 Project worked with Agriculture and Agri Food Canada to conduct studies on the herbicide pendimethalin to expand its label to include celery and other minor crops. Celery is a minor crop grown primarily in California and Michigan for fresh market and processed product sales. According to the Ag Marketing Resource Center, in 2017 California […]

Chances are if you grow green onions or bulb onions you’ve had to deal with thrips some time during the production cycle.
