Farmers who have been battling with downy mildew and botrytis recently received a boost with the launch of NoPath by Koppert Biological Systems. Its unique blend of ingredients helps to suppress plant diseases by disrupting several metabolic and biochemical processes in bacterial and fungal cells.
“NoPath alters microbial cell permeability, permitting the loss of macromolecules from the interior. It interacts with membrane enzymes and proteins, leading to an opposite flow of protons, affecting cellular activity,” Dr Nicolas Sutterheim, Koppert’s technical consultant explained.
Tests carried out on numerous farms by the Koppert team demonstrated a greater efficacy of NoPath against downy mildew and botrytis disease in comparison to normal regime of pest and disease control.
Pesticide expert, Dr Virginia Kimani: “Downey mildew has been a menace in the flower industry, while botrytis is a quality nightmare.”She described downy mildew as a “clever disease” that can manifest itself on the leaves in yellow, green or white and can grow systemically, where it penetrates the plant. The disease also attacks crops growing on vines such as cucumbers, grapes and passion fruits.
Botrytis, on the other hand, can affect up to 200 different species of crops and can grow in both living and dead tissue.Dr Stutterheim added: “The beauty of NoPath is that there is absolutely no waiting time after administering the bio-pesticide, meaning that you can spray it on your fruit and take a bite of the same fruit within the next hour with no adverse effect.”
NoPath is certified for organic farming and is sustainable in the management of the diseases. According to Dr Stutterheim, It is a long term solution because it gets into the system of the plant, making it stronger, with a higher resistance to disease attacks.
