Sticky nightshade May 14, 2016
Sticky nightshade should be sown early, preferably in May, in order to work well as green soil disinfectant. The seed is very fine. The seedbed should therefore be shallow, flat and fine, and the seed should be flattened gently. Vandinter Semo gives the seed a pretreatment as standard to facilitate germination.
Late August, the crop is mowed at 25 cm height or flailed to prevent seed formation. The crop then sprouts again. Just before digging in, the crop is flailed again. Sticky nightshade can create considerable mass. A well-developed crop yields 10 tons of dry matter per hectare. Until now sticky nightshade has not really been affected by potato diseases. In general, the crop stays healthy and it can be dug in at the end of October. If Phytophthora occurs, then it is better to plough the crop in early September. The role of sticky nightshade in the spread of Alternaria is limited. Chemical weed control is perfectly possible but not all herbicides with an authorization for potatoes are suitable/permitted.
