Spraying Roundup on Harvextra Alfalfa gives disease control

This herbicide can help to “manage foliar diseases in glyphosate-tolerant alfalfa

Greenhouse research by USDA and University of Minnesota researchers has shown that spraying glyphosate on Roundup Ready alfalfa reduces the amount of rust on alfalfa plants. When four-week old plants were sprayed with glyphosate and then inoculated with rust, the rust did not spread. 

Treatment increased protection from anthracnose and reduced symptom severity for spring black stem and leaf spot. The research report concluded that “these results indicate that glyphosate could be used to help manage foliar diseases in glyphosate-tolerant alfalfa.”

#CortevaTalks brings you a short update with Cereal Herbicides Category Manager, Alister McRobbie, on how to get the most out of Broadway® Star.

Significant populations of grassweeds, including ryegrass and brome, can threaten winter wheat yields. Spring applications of a contact graminicide, such as Broadway Star from Corteva Agriscience, can clear problem weeds, allowing crops to grow away in the spring.

Broadway Star (pyroxsulam + florasulam) controls ryegrass, sterile brome, wild oats and a range of broad-leaved weeds such as cleavers. It can be applied to winter wheat up until GS32, but the earlier the application is made, the smaller the weed, and the greater the benefit to the crop. Weeds should be actively growing. A good rule of thumb is that if your grass needs cutting, conditions are right to apply Broadway Star.
