Control Weeds, Hit Yield Targets

Control Weeds, Hit Yield Targets

(NAPSI)-The dramatic drop in glyphosate pricing this year may tempt some growers to rely on increased glyphosate rates to protect crops. But Bob Schoper, an agronomist with Winfield Solutions, cautions against that approach, since high herbicide application rates may not control some tough weeds and could lead to other problems. He offers these suggestions to achieve the best results from postemergent herbicide applications:

Boost Herbicide Performance

Follow recommended rates and maximize glyphosate performance with a good adjuvant system. Look for adjuvants that reduce fine spray droplets and improve herbicide uptake.

Monitor Micronutrients

When plants lack manganese, a postemergent herbicide application can aggravate the deficiency. The best way to identify micronutrient levels is with a simple tissue test prior to the herbicide application. If levels are marginal, add a foliar micronutrient to the herbicide tank mix.

Mix Properly

Together, glyphosate, adjuvants and micronutrients offer a plant-health trifecta, but only when mixed properly. Always add adjuvants, then micronutrients, then glyphosate.

Schoper urges growers to work with their agronomists to develop integrated strategies to achieve maximum yield potential. For more information, visit www.Agrisolutionsinfo.com.

Use tissue sampling to check manganese levels. If marginal, foliar micronutrients can enhance the glyphosate tank mix.
