A super absorbent polymer containing copper to control Plenodomus tracheiphilus the causative agent of mal secco disease of lemon

mycolabadmin

Researchers developed a new gel-like material containing copper that can fight a serious fungal disease affecting lemon trees. Unlike traditional copper sprays that wash away and pollute the environment, this new material slowly releases copper directly into the plant’s water-conducting vessels where the disease-causing fungus lives. The gel absorbed water effectively and released copper ions gradually over time, showing much better results than regular copper solutions when tested on infected lemon branches.

Inhibitory Activity of Shrimp Waste Extracts on Fungal and Oomycete Plant Pathogens

mycolabadmin

Researchers discovered that waste from shrimp processing can be converted into a natural fungicide that effectively kills plant-damaging fungi and mold. When applied to oranges, lemons, and apples artificially infected with mold, the shrimp waste extract significantly reduced rot and fruit damage. This finding is important because it offers a more environmentally friendly alternative to chemical fungicides while helping reduce the massive amounts of shrimp processing waste that typically end up in landfills or oceans.

Biocontrol of citrus fungal pathogens by lipopeptides produced by Bacillus velezensis TZ01

mycolabadmin

Scientists discovered a beneficial bacterium called Bacillus velezensis that can protect citrus fruits from harmful fungi. This bacterium produces natural compounds called lipopeptides that kill disease-causing fungi without the need for chemical fungicides. The lipopeptides are stable and effective across different environmental conditions, making them promising for use in citrus farming as an eco-friendly alternative to traditional pesticides.
