EVALUATION OF THE VIABILITY AND PROTECTION OF CONVENTIONAL AND BT CORN SEEDS UNDER INSECTICIDE TREATMENT AND STORAGE CONDITIONS
Abstract
In the process of seed production and marketing, the preservation of quality during storage is fundamental, especially until the time of sowing. A critical factor is protection against pests, such as those of the orders Coleoptera and Lepidoptera, which can cause losses of up to 20% in the stored product and compromise the germination power and vigor of the seeds. Preventive treatment with insecticides on seeds is a recommended practice to prevent pest attacks on the soil and shoots of young plants, reducing the need for later applications. Although effective, the use of insecticides can, in certain cases, cause phytotoxicity, reducing germination and seedling survival, especially when combined with fungicides. In the case of corn, treatment with insecticides is common in processing units, but there is a lack of data on its effects on genetically modified seeds (such as BT corn). The objective of the study is to evaluate the impact of the main insecticides recommended for corn crops, alone or in combination, both on conventional and BT seeds, focusing on seed germination and vigor in varying storage periods.
