Using a public dataset of 87,000 RGB images of diseased and healthy plant leaves, we train a convolutional neural network to identify diseases that are categorized into 38 different classes.

A wounding-induced VOC blend is mainly composed of oxygenated ubiquitous stress volatiles such as methanol and volatile products of lipoxygenase (LOX) pathway (mainly C5 and C6 alcohols and aldehydes and their derivatives), but also includes multiple minor VOCs that collectively act as infochemicals, inducing defences in non-damaged plant leaves and neighbouring plants and attracting herbivore enemies.

57% in aquatic plant leaves while in terrestrial plant leaves the increase was by 61.

This saprobe of moribund aquatic plant leaves is the first known rhizomycelial species in the order.

6% in rice plant leaves.

The results indicated that water stress (irrigation every 8 and 10 days) led to raising phenol content and superoxide dismutase activity in rice plant leaves, while zeolite and potassium silicate led to a decline of the plant's requirement from these antioxidants.

FCM increased chlorophyll in strawberry plant leaves and promoted plant growth, compared with control and CP.

The obtained results demonstrated a significant positive correlation between the soil nitrogen, phosphorus, and potassium levels and their levels in the Strawberry plant leaves.
