The spring update of the 2000 Guide to Crop Protection is now available at Saskatchewan rural service centres.
It contains changes that have occurred since the guide was released in January, including several new tank mixes of established products, and new registrations of products.
“For example, Amitrol 240 is a new burnoff registration for control of dandelion and annual weeds in spring wheat, barley, canola and field pea,” said Clark Brenzil, weed control specialist with Saskatchewan Agriculture.
Another important change is the registration of a spray-water amendment for Anthem and Sundance. It corrects the problems of tank residues experienced by some producers in 1999.

“The amendment raises the spray-water pH, which improves the solubility of the herbicides,” Brenzil said.
“This prevents accumulation of the deposits that caused damage to broadleaf crops sprayed after the equipment had been used to spray Anthem and Sundance.”
Compas is one of the new products listed. It is registered for use with Navigator (bromoxynil-tolerant) canola varieties. The package contains a prepack of two products: Compas Grass Herbicide (Select) controls grasses; and Compas 480E, a high-strength formulation of Pardner, controls a range of broadleaf weeds.
Another new product is Pursuit Ultra, a combination package of Pursuit and Poast Ultra. It is contained in an internally split jug, which allows both products to be dispensed at the same time. Brenzil said a light rate of Pursuit relies on Poast Ultra to control grasses.
“Everest is a new Group 2 product with a unique active ingredient, flucarbazone-sodium, that was recently registered to control wild oat and green foxtail. Everest must be tank-mixed with one of the broad-leaf tank-mix partners.”
The update doesn’t offer new crop protection products for chickpeas. Fewer crop protection products are available for chickpeas than for other crops because it is so new, said Ray McVicar, Saskatchewan Agriculture’s special crops specialist.
Products registered for chickpeas include: Apron, a seed treatment; the herbicides Poast, Select and Sencor; and Bravo, a foliar fungicide.
The Canada-Saskatchewan Agri-Food Innovation Fund minor use registration study has supplied data for registration of the three herbicides. Further products are being tested.
