Why the Potential Savings May Not Add Up

When it comes to weed control, you have lots of choices. And while going generic may seem like a cost-saving option that can give you the same results, that’s not always the case.

While many generic glyphosate brands promote lower input costs, a closer look at the numbers — and the science — may tell a different story.

Acid Equivalency (A.E.) is the measure that defines efficacy. The higher the A.E. per acre, the better the weed control. Higher use rates needed for effective control with lower A.E. products can result in higher application rates, which can increase costs and take up more room in the tank. Generic products with lower A.E. don’t always measure up when it comes to effective control and value.

 

Product Salt Lbs. A.I./G.A. Lbs. A.E./G.A. Rates (fl oz/acre)*
Generic A IPA 5.40 4.00 36
Generic B IPA 4.00 3.00 48
Roundup PowerMAX® K 5.50 4.50 32

*Use rate needed to supply 1.125 Lbs. A.E./A

By the Numbers

Generic A and B have a lower A.E. per gallon than Roundup PowerMAX® herbicide. The A.E. defines efficacy as the higher the A.E. applied per acre, the better the weed control. Based on the A.E. of Generic A and B, you would have to apply a higher rate of generic product to get the same amount of glyphosate acid per acre as Roundup® agricultural herbicide.

 

 

As you can see in the above graphic, the lower A.E. of Generic B means you would need 1.5 times the amount of Generic B to match the spray rate of Roundup PowerMAX® herbicide. More product can mean more money spent, so though the initial price of generic products may seem appealing to your budget, you may be paying for that efficacy in the long run. In fact, if you have a 3,000-acre farm you would have to purchase 375 more gallons of Generic B to match the recommended spray rate of 32 fl oz/acre of Roundup PowerMAX® herbicide.

Salt Makes a Difference

Most generic glyphosate products are in the form of an Isopropyl Amine (IPA) salt. Roundup® brand agricultural herbicides are formulated as Potassium (K) salts. The difference in the densities of these salt solutions allows for a higher load of glyphosate acid in K-salt formulations, which is why you can use less Roundup® brand agricultural herbicides per acre compared to most generics.

Don’t be Fooled by Initial Costs Alone

When choosing your glyphosate formula this season, make sure to crunch ALL the numbers to ensure you’re not just getting savings on the surface, but that you’re getting the effectiveness you need to see success in the fields.

Not only are Roundup® brand agricultural herbicides the real deal in weed control, they are the ONLY glyphosate brand that can qualify you for additional savings through the Roundup Ready PLUS® incentive program.
