All-rounder Signum remains a fixed value
The dosage of Signum in potatoes has recently been increased from 0,20 to 0,25 kg/ha. This gives growers a robust dose to combat alternaria and sclerotinia.
The broad effect on many fungal diseases and the approval in, for example, potatoes, onions and carrots have Signum a popular product among arable farmers. In the cultivation of potatoes, Signum can be used effectively against the pathogens alternaria and sclerotinia.
Alternaria
The fungus Alternaria solani is a weakness parasite. A potato crop that is not in optimal condition can easily be affected and lose a lot of leaves in the foreseeable future. To prevent alternaria, specific alternaria products should be applied from mid-flowering. Start with Signum and then alternating with other alternaria agents gives the best result.
sclerotinia
Sclerotinia (rat droppings disease) is a fungus that can affect many plant species. Sclerotinia causes spot wilting and death of plants. The fungus survives for a long time in the soil in the form of sclerotia (resting spores). These are dark granules of fungal thread that resemble rat droppings.
Potato growers are increasingly finding sclerotinia infestation in their crops. This means that the pressure from the bottom increases. Especially in rotations with vegetable crops or rapeseed, there is often an increased pressure. If sclerotinia is insufficiently controlled, the number of sclerotia will increase and problems can be expected in succeeding crops. Sclerotinia is already more common in seed potatoes, but it is a growing problem in consumption and starch cultivation.
BASF's research in seed potatoes has shown that Signum can cause up to 80% less stem damage. The condition is that the application is started on time. Starting before closing the crop gives the best effect.
