A new way to combat resistant pests stems from discovering how the widely-used natural insecticide Bt kills insects. Figuring out how Bt toxins punch holes in the cells of an insect's gut was the key ...
WEST LAFAYETTE, Ind. - Volunteer corn can act as a safe harbor for some pests by expressing lower doses of the insecticide found in newly planted corn, according to Purdue University researchers.
MANKATO, Minn. - If a farmer cuts costs on corn foliar fungicides and Bt (Bacillus thuringiensis) insecticide treatments, will it cost them later in rootworm and corn borer damage? Bruce Potter, ...
Critics often raise concern that genetically engineered crops might harm the environment or people who eat them. But now a new study finds that farmers who plant Bt corn reduce crop damage and ...
Research shows that the commonly used and naturally occurring bacterial insecticide Bt works best if applied to young plants and is enhanced by the presence of the insect pests. Spraying Bt -- the ...
Pesticide use is surging among U.S. farmers who are worried about insect resistance to Bt corn. But scientists warn that overuse of chemicals may create a worse problem down the road. Pesticide use is ...
WEST LAFAYETTE, Ind. -- Planting Bt corn fence row to fence row could potentially eliminate it from farmers' list of options for pest control, two Purdue University entomologists warn. The corn is ...
A cocktail of insecticides containing a plant protein and a common insecticide may be more lethal to crop pests than either ingredient used alone, according to biologists. The one-two punch also ...
A collaborative team of researchers just used viruses to chivvy along evolution, resulting in a new bacterial toxin useful on pesticide-resistant insects. It calls to mind that old saying: the enemy ...
The first field test of a strategy for controlling insect resistance in a crop engineered to carry genes from the pesticide-producing bacterium Bacillus thuringiensis confirms the value of refuges in ...
