Understanding the Opportunities to Mitigate Carryover of Imidazolinone Herbicides in Lowland Rice

(1) Background: The Clearfield™ system (CL) is currently the primary tool for selective weedy-rice management in irrigated rice. However, herbicide persistence soil may cause damage to successive crops. Thus, it necessary understand agricultural practices that can favor dissipation of these herbicides. objective this study was analyze factors affect imidazolinones and use information provide strategies mitigate carryover lowland (2) Methods: A literature review performed, publications were selected using half-life parameter. data summarized according biotic conditions, parameters, environmental variables. (3) Results: Imidazolinone occurs primarily through biodegradation. biodegradation rate depends on conditions such as temperature bioavailability soil. Herbicide affected by with higher pH, less clayey texture, moderate organic matter content, moisture levels. Therefore, biological activity, especially high temperatures, reduce Strategies should focus improving availability enhancing activity soil, rice off-season, when low temperatures limit Cover rotational crops, ryegrass soybean, are recommended, potential residues. (4) Conclusions: establishment crops other than would automatically enhance degradation rates amendment pH correction drainage activity.
