herbicide for the control of horseweed Conyza spp and other weeds

[Category : - CHEMISTRY- Agriculture- Organic Chemistry]
[Viewed 79 times]

Here is the English translation:rnrnThis is a contact herbicide, currently undergoing patent protection with the INPI (application no. BR 10 2025 011191-8), developed for the effective control of horseweed (Conyza spp.) and with potential application to other weed species, especially broadleaf weeds. The technology was conceived to meet the growing demand for more sustainable and economically viable solutions for weed management in agricultural systems.rnrnThe formulation is based on a combination of acetic acid, ammonium sulfate, vegetable oil, and a biodegradable surfactant in an aqueous medium. The product acts by contact desiccation, rapidly causing necrosis of leaf tissues after application, without relying on systemic modes of action typical of many traditional herbicides. This characteristic makes it particularly attractive in scenarios of resistance to herbicides already established on the market.rnrnOne of the differentiating features of this technology is its low production cost, due to the use of inputs widely available in the chemical and food industries, which can favor industrial scalability and price competitiveness compared with existing products. At the same time, the selection of components and the mode of action are designed to reduce environmental impact when compared to highly persistent synthetic molecules, contributing to more sustainable agricultural practices and compliance with increasingly strict regulatory requirements.rnrnPreliminary trials under controlled and field conditions have demonstrated good efficacy in the desiccation of horseweed, including larger plants, and indicate potential use against other weeds, creating opportunities for future label expansion for different crops and management systems (for example, pre-planting in grain production, management in border areas, orchards, and no-till systems).rnrnFrom a business standpoint, the patent offers opportunities for:rnrn* Licensing the technology to companies in the crop protection sector, special inputs, or sustainable solutions for agriculture;rn* Co-development up to the product registration stage with the relevant regulatory authorities;rn* International expansion through protection strategies via the PCT and subsequent entry into key grain- and fiber-producing markets.rnrnThe goal is to attract investors and strategic partners interested in participating in the development, registration, production, and commercialization stages of this contact herbicide, leveraging its potential to generate economic value while contributing to a more efficient and sustainable agriculture model aligned with new market demands.rn
