Rotam do Brasil recently launched a herbicide to combat annual and perennial grasses, most notably sourgrass (Digitaria insularis), as well as for use during the pre-sowing management (desiccation) of soybean. Freno 240 EC (clethodim) has a post-emergent systemic action and is highly selective for cotton, garlic, potato, coffee, onion, carrot, beans, tobacco, cassava, watermelon, soy and tomato crops.
Sourgrass is a common problem in the country and is often resistant to the active ingredient, glyphosate
. According to the head of the company's research center, Carlos Guarnieri, sourgrass is an invasive plant that is common in several regions of Brazil, especially in the southeast, infesting major annual and perennial crops. “For example, soybean yield loss can be up to 80%. This is a species with a high reproductive capacity, and the plant can produce 100,000 seeds,” he said.
To prove the effectiveness of Freno 240 EC, Rotam's team tested its new product, along with glyphosate, on soybean at its Mapa-accredited research center in Artur Nogueira-SP. The results showed that after 29 days of treatment, the product’s eradication efficiency was 100%. “We realized from this experiment that the product can achieve beneficial results for producers. This is a new tool available to farmers for improving crop productivity,” said Lucas Ferreira, Marketing Coordinator at Rotam do Brasil.
