Masking the Corn Rootworm

Jun 11, 2013

In drought-stressed regions, corn rootworms thrive. 

Drought plus corn rootworm infestation presents a compounded problem to farmers: The bugs proliferate under dry conditions and the damage their incessant root feeding does to plants, like stunting growth and limiting ear fill, is magnified by heat stress and lack of water.
In 2012, severe drought masked the severity of the corn rootworm problem. Rain and wind storms typically make rootworm-damaged corn plants fall over but the rainstorms didn’t come in 2012.
By reducing water and nutrient uptake of plants, larval root pruning places severe physiological stress on corn and results in significant yield reduction. At a time when scientists are predicting more-frequent severe weather events, crops are more vulnerable to corn rootworm damage.
Be on the lookout for a brand new corn rootworm technology from Syngenta in 2014.
