In Brazil, Bayer announced the launch of the insecticide, Curbix, for the control of boll weevil (Anthonomus Grandis Coleoptera
) in cotton. With a new active ingredient, ethiprole (200 g/L), the product provides a prolonged shock and residual effect on pest control, which causes damage to fiber producers. AgroPages
exclusively interviewed Gerhard Bohne, President of Bayer's Crop Science division in Brazil, about this new solution presented in the country.
How important is Curbix in resistance management?
It works to manage weevil resistance, which is a serious problem in some regions of Brazil and requires a battery of insecticide applications. Curbix, possessing a mode of action that is different from other insecticides available in the market today, helps in the management of boll weevil in various regions of Brazil.
What is the difference in your new active ingredient?
It has a shock effect and a residual effect, in addition to contact and systemic effects, so it is a product that really helps in controlling the weevil longer, and it also has a very good residual effect. Its use is indicated for insecticide resistance management programs. In this way, it is possible to reduce the selection pressure of insects less sensitive to pesticides and maintain high levels of pest control in the crop.
What are the next steps for Bayer?
We have several chemicals we are developing for growing cotton, such as Sivanto Fusion, which is a mixture of insecticides for the insect complex. Verango is a product that will offer control for nematodes in cotton. There is also Apl, which we will bring in the future to the final phase of cotton, to the ripening and defoliation phase.
In biotechnology, we have an entire pipeline for the next few years. We are developing Bogard 3, Xtend also for cotton, as well as a new generation of other herbicides and insecticides, more Bts (Bacillus thuringiensis) to introduce Bogard 4 technology, but that's for the medium-term future.
