Are there different types of glyphosate?

There are several glyphosate salts currently available in the market and others have been in the past but are less common now. Four examples (below) include: isopropylamine, dimethalamine, trimesium, and potassium salts. (images mostly lifted and modified from

What is the formulation of glyphosate?

Glyphosate products use several forms of glyphosate salts. The major salts in glyphosate products are potassium, isopropylamine, ammonium and trimesium. Potassium refers to the salt form of glyphosate acid from monopotassium (K). Isopropylamine salt has a “propyl chain” (3-carbon chain) and an amine group.

Is Imazapyr better than glyphosate?

Imazapyr is a great alternative to Glyphosate and has a number of advantages over Glyphosate such is a quicker drying time. Manufacturers claim it is rainfast within 1 hour. This leads to a higher uptake of Imazapyr into the plant vs. Glyphosate.

Is glyphosate safe for wildlife?

Can glyphosate affect birds, fish, or other wildlife? Pure glyphosate is low in toxicity to fish and wildlife, but some products containing glyphosate may be toxic because of the other ingredients in them. Glyphosate may affect fish and wildlife indirectly because killing the plants alters the animals’ habitat.

Is Gly Star Plus like Roundup?

Gly Star Plus is a generic version of Roundup for the non-selective control of plants. A concentrated formulation of glyphosate, Gly Star Plus is mixed with water and control plants to the root. For quicker results or to control tougher weeds, Gly Star Plus can be tank mixed with many different herbicides.

What is a good substitute for glyphosate?

Several other non-selective herbicides are available for use in landscape plantings. These include: Diquat (Reward™), pelargonic acid (Scythe™), glufosinate (Finale™ and others), and many “natural products” such as vinegar and botanical oils. All of these products have contact-type activity.

Is glyphosate bad for the soil?

Glyphosate “locks up” manganese (PDF) and other minerals in the soil so that they can’t be utilized by the plants that need them. It’s also toxic to rhizobia, the bacterium that fixes nitrogen in the soil.

What should you know about different glyphosate formulations?

Glyphosate formulations vary in performance but differences are often weed species specific. In-tank adjuvants may both enhance or detract performance of glyphosate formulations. Targeted use of adjuvants can assist in maintaining high level of weed control alongside other factors.

Is the acid in glyphosate the same as the salt?

Of course, the glyphosate acid weight is the same C 3 H 8 NO 5 P in each formulation – only the salt is different. So, it is important to remember that in these herbicides the “active ingredient” (AI) is the salt formulation (eg glyphosate isopropylamine) and that each of the different active ingredients has a slightly different weight.

How many G of glyphosate are in Roundup?

The name of the active ingredient and its concentration are given on the front panel of the label under the product name. For example, the herbicide Roundup contains 360 g/L of the active ingredient glyphosate. This means that in 1 L of Roundup product or concentrate, just over one third (360 g) is the active ingredient glyphosate.

Why are there different glyphosate salt formulations for weeds?

The salt formulations are those of us managing weeds for a couple of important reasons. First, the different glyphosate salts have different solubility in water (or other solutions). Second, the different glyphosate salts have different weights.
