Potato: It is applied directly to the soil surface after planting potatoes in pre-emergence, no other application is required. 50-75 g/da are applied to light soils and 75-100 g/da to heavy soils. 50-75 g/da are used when the potatoes are 5-10 cm tall in the post-emergence. Tomato: 50-75 g/da are used when tomatoes grow from seedlings, when the seedlings catch a few days after transplanting and most weeds come to the surface. When growing tomatoes directly from seed, a) 30 g/da are applied before tomato seedlings come to the surface in pre-emergence. b) 40-70 g/da are applied when tomato seedlings have 6-7 leaves in post-emergence. Soy: It is applied immediately after sowing. No other application is required.
