Nealta insecticide offers benefits for beneficial insects.

RSS

Strawberry growers in the West often use beneficial insects – also known as Persimulus – to help keep  two-spotted spider mites from reaching damaging levels in their strawberry fields.

“There will always be some level of mites in the fields,” said Doug Haller, product manager for BASF. “So what they’re trying to do is to keep that level where it’s not creating damage and causing yield and quality loss.

“So these beneficials are there to help them. But every once in a while the mites get out of control, and the beneficial mites need some help. There are products out there that will wipe out a good part of the beneficial mites as well. What’s neat about Nealta is that growers who have invested in beneficial insects can use Nealta and not eliminate their beneficial mites.”

Haller was one of several speakers who talked about BASF’s new product lineup at the company’s Holly Springs Research Station outside Raleigh, N.C. He was interviewed during a break at the BASF Ag Media Summit in June.

Besides being more forgiving on beneficials, Nealta also has other advantages: It contains a new mode of action; it is active on all four life stages of two-spotted spider mites; and it appears to act more quickly – within six to eight hours – while providing longer residual control.

Nealta’s unique site of action is not found in any other miticide in the U.S. Cyflumetofen, the active ingredient in Nealta miticide, is highly effective against mites which may have developed resistance to other acaricides.

Nealta has received registration from EPA for use on almonds, pistachios, grapes, strawberries, apples, and pears. Registration is pending in California, but Haller is hopeful the product will receive clearance from the California EPA this fall.
