There are limited options for curative control allowed under organic agriculture guidelines, which vary from country to country. Curatives are inputs to the crop production system that are applied after a pest or pathogen has established in the crop, and threatens to reduce yields if action is not taken. Table 4.1 provides a representative list of botanically derived pesticides, microbial agents and other naturally available materials typically approved under organic standards. These materials vary in their toxicity levels and non-target effects.
