Application Information
Beans
:
DCT seed treatment may be applied as a water-based slurry through standard slurry or commercial seed
treating equipment. Dry the seed before seeding or bagging. For best results, seed should be planted within a
week after treating. Do not store treated seed more than one month before planting. This product will not control
anthracnose if seed is severely infected.
Corn
:
When starting with an empty planter, place enough treated seed in the planter box to cover the bottom. Treat
this seed in a separate container that later can be destroyed. Add the remaining seed to the planter box and treat by
thoroughly stirring with a paddle so that the seed is coated with the seed treatment.
How it Works
DCT is a dual-purpose seed treatment, containing three active ingredients. Diazinon is an organophosphate
insecticide that kills the root maggots by contact and stomach activity. The active ingredient captan is a phthalimide
fungicide, controlling the seedling blight and root rot with multi-site activity, and thiophanate-methyl is a methyl-
benzimidazole carbamates with systemic activity on anthracnose and other seed-borne diseases.
Restrictions
Do not use treated seeds for food, feed or oil processing.
