Fungicides

Vitaflo 280 from Bayer was reissued in Canada with an improved formulation that seems much friendlier. It stays in suspension better and doesn't dust off as badly. It still requires mid to high rate for Fusarium and smut, but offers broad-spectrum economic control, and can be used on both cereals and pulses.

Syngenta's ApronMaxx RTA fungicide came to Canada last spring for application on soybeans and all pulse crops. AM has been registered in the U.S. for 2 years, and has taken over most of the soybean fungicide market due to it's very broad spectrum control. The revised label now includes control of seed borne ascochyta and botrytis in lentils and chickpeas, and seed borne phomopsis in soybeans. Its ability to tank mix with insecticides or inoculants allows 1 shot application of up to 3 seed treatments at once.

Agriliance's Incentive RTA was released last spring to provide additional pythium control in cereals. It's aimed at high moisture production areas, where diseases are more punishing on crops.

Insecticides

Although they're not fully registered, the new class of seed placed insecticides (Cruiser, Gaucho, Poncho) were used in several emergency situations last spring to deal with specific pest outbreaks. They appear to have major crop benefit by supplying longer duration protection from insects with a seed-applied product.

Cruiser was co-applied with Dividend on southern Canadian prairie cereals to combat wireworms in land going into potatoes next year.

Cruiser and Gaucho were co-applied with fungicides on Iowa soybeans with good results. Cruiser will likely be registered in 2005 on U.S. soybeans, with Gaucho following a year later. Our G3-1100 applicator systems were widely used to apply the tank mix of fungicide + insecticide and performed very well, according to the operators. Many used G3DS™ double shoot systems so they could apply fungicide / insecticide mixes, with inoculants delivered by the second gun.

Idaho had an outbreak of barley attacks by mealy bugs, so again fungicide / insecticide mixes were seed applied to control the pests. Dry weather lowered bug numbers this year, so it's not clear how effective the seed treatments were. Dividend Extreme / Cruiser pacs and Raxil / Gaucho 480 tank mixes were G3 applied to deliver the treatments.

Cruiser will come out in 2 formulations; 5FS for the U.S and 350FS for everywhere else. They're the same product; just different concentrations. Canada will be using the 350FS formulation. We will have calibrations for them both.

Phosyn from England has started to market their European line of micronutrients into North America. Zinctrac is being applied to fertilizer with P2/19A applicators and last spring Teprosyn, a zinc/phosphate product was G3 applied to cereals and bean seed. In the U.S., Agriliance is investigating adding Iron-clad, a mix of Warden with chelated iron to seed treatments to increase yields on iron chlorotic soils.

Seed placed micros are widely used in Europe and provide good economic returns in specific areas. It will take time to define the best soils response from seed placed micros, but the practice is attracting wide interest from agronomists.

Seed placed products have the benefit of being immediately available to the plant, from the time of germination. Advantages over post emergent micro applications include much lower cost, free application and better placement accuracy and targeting of the benefit.

We create pre-calibrated application charts for major new seed treatments as soon as they are registered. If you have a G3 or A4 applicator and need calibrations for a new product, just give us a call.
