 Are there actual differences between all the glyphosates on the market or are they basically the same?
A few years ago all glyphosate products had acid equivalent (ae) concentrations of about 360 g/L, but now products have ae concentrations of 360, 450, 480, 500 and 540 g ae/L (Table 1). Because of these ae concentrations, volumetric application rates are no longer standard for all products (Table 2), and care must be taken to ensure that products are applied at the proper rate for intended results. Except for these ae concentration differences, many of the glyphosate products are similar, with similar activity on weeds but keep in mind that each of these herbicides has a unique label that defines how the product can be legally used and what results can be expected if the product is applied according to label.

For preseed burnoffs, what can be mixed with glyphosate for improved weed control?
Glyphosate tank mixes for preseed situations are one area where there is some variation between product labels. Pardner at 0.4 to 0.5 L/ac, Express and Express Pro are the only products that have registered mixes with all glyphosates. Buctril M, Banvell II, 2,4-D (amine or ester), and MCPA (amine or ester), have registered tank mixes with all, of the various glyphosate products.

Recently, there have been a couple of glyphosate tank mixes registered for burnoffs prior to seeding canola. These are Conquer + glyphosate and Pardner plus glyphosate. Only MCPA amine and Express SG are registered for mixing with glyphosates prior to peas. However there are restrictions. Check the Express label prior to use. Heat and glyphosate can be used preseed for peas, chickpeas, and lentils (lower rate of Heat for lentils). Also note that the 2,4-D rates in Table 2 are based on acid equivalent concentrations of 560 g/L (of 2,4-D) and these rates need to be adjusted if other formulations are used. Due to the sheer numbers of glyphosate products, it is difficult to present all the products and their registered mixes. Check the individual labels for tank mix partners.

In Roundup Ready Canola, is weed control the same for all registered products?
Annual broadleaf and grassy weed control is similar for all the glyphosates registered for use in glyphosate tolerant canola (Table 3). Crop staging(up to 6 leaf stage) is the same for all registered products, as is the maximum total annual post emergent application rate of 360 g ae/ac.

For perennial weed control all products are registered for a single application of 270 g ae/ac to give full season control of Canada thistle and perennial sowthistle, (Table 3).

Weeds Controlled
Comments
119 - 180 g ae/acBarnyard grass, chickweed, corn spurry, green foxtail, hempnettle, kochia, lady’s thumb, lamb’s quarters, redroot pigweed, Russian thistle, stinkweed, volunteer barley, volunteer canola (non Roundup Ready), volunteer wheat, wild mustard, wild oats, wild tomato.

Cow cockle, night flowering catchfly, and shepherd’s purse controlled with the low rate only when weeds are in 1 - 3 leaf stage. Smartweed at 4 - 6 leaf stage also controlled with the low rate. For all other stages of these weeds use the high rate.
Glyphosates have no
residual activity. Repeat
applications may be
required if a second flush
of weeds germinates prior to canopy closure.

Ensure the crop has not
advanced beyond the 6
leaf stage.
