Swell of Heat Brings Swarm of Pests

July 12, 2021

Droughts not only damage crops but also welcome grasshoppers looking to feast.

The threat of insects steadily increases as drought conditions continue to stretch across the country. Unprecedented temperatures not only damage cereal crops by drying out soil and leaving little water for plants to nourish themselves with but also open the door for damaging pests looking for a place to thrive. Grasshoppers are among the most feared insect threats in very dry or drought conditions which fosters ideal weather for swarms to develop.

This is a problem now with widespread droughts in the Northern Plains and throughout the country.

North Dakota State Extension Service states that grasshoppers flock towards cereal crops whenever drought conditions arise, increasing populations and leading to hot spots and localized outbreaks. They remind growers to be aware of grasshopper movement into row crops as cereal grains are dried down and harvested.

Grasshoppers can limit yield by chewing plants, limiting photosynthesis and even clipping heads in wheat and barley, devastating crops already suffering from drought stress.

Besiege® insecticide protects cereal growers against unyielding grasshoppers during drought by providing an effective management option for growers. Besiege provides powerful broad-spectrum control to battle chewing insect pests like grasshoppers on contact, ingestion and through ovicidal action. Chlorantraniliprole and lambda-cyhalothrin offer dual modes of action to stop pests from jeopardizing your yield potential.

For more information on protecting your cereal crops during extreme weather conditions, contact your local retailer or Syngenta representative.
