Host of Crop Protectants Get Approved

Check out these newly cleared products for 2008 use.

Published on: May 7, 2008

Even as farmers head out to plant, a host of new or expanded pesticide labels keep receiving approval by U.S. Environmental Protection Agency. To keep you up to date, here's a quick rundown on the ones we know about:

Soybeans and tubers get Hero

Hero foliar insecticide, from FMC, is now labeled for soybeans, plus root and tuber crops (including potatoes). Its pyrethroid technology teams up for fast knockdown and longer-lasting residual control of foliar pests, according to FMC Product Manager Adam Prestegord.

It's labeled for soybean aphids, fall armyworm, velvetbean caterpillar, thrips, cabbage looper, Japanese beetle (adults), stink bugs and army cutworms, among others. And, Hero controls mites without flaring them. Hero's label carries a "caution" regarding a 12-hour field re-entry interval.

A Cadet rescue for corn and beans

Cadet postemergence herbicide, also from FMC, is labeled for superior control of velvetleaf, pigweed, lambsquarters, waterhemp and nightshade in corn and soybeans. Low rates of its fluthiacet-methyl active ingredient standard rate even controls resistant biotypes.

"Cadet is an effective, flexible tool for rescue management of velvetleaf and other troublesome broadleaf weeds," says FMC product manager Yemel Ortega. "It eliminates weeds that glyphosate, alone, just can't control."

It's also labeled for control of jimsonweed, burcucumber, spurred anoda, and others. It's effective on velvetleaf up to 36 inches tall.

Cadet carries a 60-day pre-harvest interval for soybeans and a 90-day PHI for corn. It can be tank mixed with glyphosate or other postemergence herbicides.

Temprano for early-season mites

Chemtura recently launched this abamectin-based miticide for quick knockdown and long residual control on more than 40 crops, including tree fruit, vine and vegetables.

It's most effective as an early preventative spray to control two-spotted spider mites, European red mites, thrips and leafminers. Featuring translaminar action, Temprano finds pests where they hide – under the leaves.

Leverage soybean insects

Leverage 2.7SE insecticide, from Bayer, is registered as a broad spectrum control of soybean aphid, bean leaf beetle, Japanese beetle and corn rootworm beetles.

With surface and translaminar activity, it protects both the upper and lower sides of leaves. "With the two modes of action," says Ed Keane, Leverage product manager, "it's a resistance-management tool."

Fruitone pome thinner now in liquid

Fruitone, from AMVAC, now comes in a liquid formulation. The plant growth regulator is used for fruit thinning, return bloom enhancement and pre-harvest drop control in apples and pears. It's labeled for use in Massachusetts, Michigan, New York, North Carolina, Ohio, Pennsylvania and Virginia.

The new formulation performs equal to or better than the powder for thinning, says Product Manager Kyle Coleman. And it gives growers greater flexibility with regard to timing and rates for thinning, return bloom and pre-harvest drop.

Nail mites with Zeal

Zeal miticide, from Valent, offers long-lasting residual control in cherries and melons of two-spotted spider mite, European red mite and Pacific spider mite in a single application. It's available in all states except California and New York.

Zeal affects all life stages of mites—eggs, larvae and nymphs—on contact, and eggs laid by treated adults will not hatch. While it has translaminar activity, it's also soft on beneficial insects and mite predators.

Arrest bean rust with Proline

Proline 480SC fungicide from Bayer recently received labek approval for control of Asian soybean rust and powdery mildew. It can be tankmixed with Stratego, reports Jim Bloomberg, Bayer fungicide product manager, "for preventive and curative activity." It can be applied with either ground or aerial application equipment. It's not yet registered in all states.

Prowl H2O gets grape label

Prowl H2O, from BASF, is now labeled in New York for use on grapes, including table, raisin and wine varieties. This formulation has less odor, produces less staining, contains no VOCs and doesn't bind to field surface residue like organic solvent-based products, reports Jon Sweat, Prowl marketing manager.

"Due to its water-based formulation, Prowl H2O is ideal for grape growers looking for long-lasting, reliable weed control in an easy-to-handle, highly compatible tank-mix herbicide," he adds. "Because it's less volatile, it delivers better residual broadleaf weed and annual grass control."
