In Peru, the Second Chamber of the Constitutional Court ordered Senasa to temporarily suspend the sale, distribution, and use of several phytosanitary products. This includes pesticides containing chlorpyrifos, methomyl, glyphosate, imidacloprid, and clothianidin used for domestic vegetable production. The ruling mandates a technical-scientific re-evaluation of these substances to ensure food safety.
