Safe for humans [...] reduces the environmental impact but also minimizes the risk of pesticide resistance, making it a sustainable and effective long-term strategy for pest [...] lly friendly products, the demand for biological pest control methods is likely to grow, making it a forward-looking choice for agriculture and pest management

• Botrytis

  es unfavourable for germination, the spores can survive a few days on the plant surface and still germinate when the RH increases, for example when cut [...] part of the foot rot complex, which causes rotting of the foot and may cause death of the plants. In cucumber and tomato the fungus causes lesions on pruning [...] that it excretes compounds that kill the plant cells and then uses the content of the plant cells as nutrients. On the infected area, new spores are formed

The bacterium Candidatus [...] potato psyllid amplifies the feeding damage and causes ‘zebra chip’ in potatoes Indirect damage causes the most harm, since the consequences are wide-ranging

Competition for nutrients: Trichoderma harzianum competes for resources, such as space and nutrients, thereby reducing the availability [...] diseases through various mechanisms. Competition for space: Trichoderma harzianum grows faster on the surface of the root than soil borne pathogenic fungi, which [...] Induced resistance: Trichoderma harzianum reinforces the defence mechanism of the parts of the plant above the ground, so-called induced system resistance (ISR)

• Downy mildew of rose

  They cause lesions on the upper leaf surface, bordered by the veins, which are first yellow and then turn brown. On the underside of the leaf fluffy growth [...] and the germ tubes infect the plants either through the stomata or directly by penetrating the cuticula. For germination free water is required. For most [...] mildews, the optimum temperature is around 15 °C. The closer the temperature is to these 15 °C , the shorter the leaf wetness period that is required for germination

An overview of positive attributes of microbials depending on the organism: [...] colonize the roots and protect the crop during the entire growing season. Seed treatment increases the availability of plant nutrients in the root system [...] applied to the seed in a powder form or as a liquid. An even layer covers the whole seed. In this way, the beneficial ingredients are available to the seed when

On potato [...] from the root to the foot, but direct infection of the foot also occurs. Exudates leaking from growing root tips promote germination and attract the zoospores [...] zoospores.

The mites are mostly found within the flower buds, growing [...] in localized patches, because the mite spreads very slowly. Symptoms vary depending on the host plant and can resemble the damage caused by viruses. Infested [...] become brown near the base.

While the trend towards organic farming was [...] organic farming marks the path to the future. "You grow into it a bit," notes Koen. With the growing availability of knowledge and the number of biological [...] believes that the reduction of chemical methods paves the way for organic alternatives that can complement traditional farming practices. For him, it is clear

• Pea blight, leaf and pod spot

  January 1, 1970

  pisi causes spots on leaves, stems and pods of peas. The spots on leaves and pods are round, on the stems they are more elongated. The lesions are light [...] transmitted on the outside of the seed coat and cause primary infection. The conidia germinate and infect through the stomata or directly through the cuticle [...] surrounded by a dark brown to red-brown border. The first infection is often on the primary leaves. The fungus is seed borne and thus also causes post-
