Just above the damaged area, the roots produce large numbers of new branches. This ultimately results in a reduced

The most direct damage is caused by the larvae mining the leaf tissue, leading to desiccation, premature leaf-fall and cosmetic damage. In tropical [...] gerbera and chrysanthemum.

In open field environments, bees are among the most efficient and reliable pollinators. Their foraging activities enable the cross-pollination [...] pollen proves instrumental in promoting robust pollination and contributes to the development of more uniform and larger fruits and vegetables, ultimately

Induced resistance: Trichoderma harzianum reinforces the defence mechanism of the parts of the plant above the ground [...] harzianum grows faster on the surface of the root than soil borne pathogenic fungi, which get no change to establish themselves on the roots. Competition for [...] improves the root system through the formation of more root hairs, so that water and nutrients can be absorbed better. This leads to a stronger and more uniform
