Research findings at the University of California, Davis, might help growers apply insecticides to control spotted wing drosophila when the insect is the most vulnerable.

The pest, Drosophila suzukii, infests soft-skinned fruits, including cherries, peaches, grapes, and various berries. It is not controlled by the GF-120 bait commonly used to [...]

A  British biotechnology company is developing a novel new way to control insect pests. Called RIDL, which stands for Release of Insects with Dominant Lethality, it works somewhat like sterile insect releases.

Instead of using radiation to create sterile male insects that mate ineffectively with females, lethal genes inserted into a [...]

New spray concept proves feasible

  • September 1st, 2013

If we had to irrigate orchards by pulling tanks of water down the alleys, would we do it?

We do that now with pesticides and plant growth regulators, hauling loads of water with small amounts of chemicals in them, then blasting the mixtures into the trees.

Only about a year ago, [...]

  • September 1st, 2013

Precise application of pesticides in orchards provides growers with better crop protection, less environmental pollution, and better use of resources. It costs less when pesticides are not wasted.

Since coming to Cornell University in 1998, Dr. Andrew Landers has been working to make airblast canopy sprayers, designed more than 50 [...]
