Discipline insecticide for corn

A broad-spectrum corn insecticide called Discipline 2EC recently received registration approval for control of insect pests in corn. The insecticide by AMVAC contains bifenthrin, which is a pyrethroid insecticide used to control corn insects such as cutworms, corn rootworms, armyworms, and corn borers and mites.

According to AMVAC, Discipline offers application flexibility, broad-spectrum and long residual insect control, and a low active ingredient use rate. It may be applied alone or with herbicides or fertilizer as a broadcast preplant incorporated or preemergence spray; applied at planting over the row with liquid banding or other liquid application systems; or applied as a foliar spray. Application rates range from 2.1 to 6.4 fluid oz./acre.

Water-based Prowl

A water-based version of Prowl herbicide with the active ingredient pendimethalin is now available from BASF. Because the product is water based, it is stable, rainfall-patient and easily tank mixed, according to BASF. It possesses no incorporation window.

The company states that other benefits of the product include no odor, reduced staining, greater storage temperature flexibility and a use rate that is lower than that of other pendimethalins. The herbicide is labeled for a wide variety of crops, including corn, grain sorghum and soybeans. Limited quantities of Prowl H2O are available for 2004.

Gene bank support

DuPont recently announced a pledge of $1 million to the Global Crop Diversity Trust. The trust provides financial support to world gene banks that store plant germplasm and crop diversity collections. The collections are available to public and private plant breeders and farmers under the terms of an International Treaty on Plant Genetic resources. The trust hopes to raise a $260 million endowment that will support the collections, especially in developing countries. It currently has pledges for $44 million.

Ready for soybean rust

A systemic fungicide that treats soybean rust has received a quarantine exemption from EPA in the event of an infestation in the United States. EPA granted a Section 18 quarantine exemption for myclobutanil to be used for soybean rust in Minnesota and South Dakota. Dow AgroSciences products formulated with myclobutanil are Laredo EC and Laredo EW. Dow is working with other states to obtain the Section 18 exemption.

Spring wheat variety

A new high-quality spring wheat variety derived from an Argentine variety and a University of Minnesota variety will be available in 2005. The new variety Banton may be purchased from Trigen Seed. The mid-season, semi-dwarf, hard red variety has rust resistance and strong straw with a bright finish at maturity. Trigen Seed decided to release Banton after a milling and baking industry panel gave a favorable assessment of its quality for bread making.

RR alfalfa in 2005

Expect Roundup Ready (RR) alfalfa to hit the market in late 2005, says Dan Undersander, University of Wisconsin Extension forage specialist. Forage Genetics International and Monsanto are currently working with various marketing and breeding partners to bring the product to the market, Undersander says. “This will be the first forage crop coming out with a biotech trait in it, and the testing and studies have been very comprehensive,” he explains. “Monsanto and Forage Genetics are seeking clearances for the product in Japan, Mexico and Canada to make sure there will be markets for the hay.”

Seed production is under way on six to eight varieties of RR alfalfa to meet market demand when clearance is achieved, Undersander reports. — e-Hay Weekly Newsletter
