Introduction
Anthracnose is a common
and serious disease of plants in tropical region and humid areas. It is a
fungus that causes heavy and deep damage to tomatoes making it easy to rot.
Growth of Anthracnose (C. Coccodes) is most rapid at 80° F, although the
fungus can cause infections over a wide range of temperatures (55°-95° F). Wet
weather promotes disease development, and splashing water in the form of rain
or overhead irrigation favors the spread of the disease. Colonies as observed
by the researchers are usually dark pigmented with white aerial vegetative part
of a fungus which is called mycelium. Consisting of numerous black compact mass
of hardened fungal mycelium containing food reserves (sclerotia) and light
brown colored conidial masses, reverse is a dark brown conidial masses. It is
also a result in wide range of symptoms like leaf spots, defoliation and
distortion in many different kinds of plants. One of the plants that is
affected by this kind of fungi are tomatoes.
The researchers have come up with the idea of
using Madre de Cacao (Gliricidia sepium) leaf extract on post-harvest Tomatoes
(Solanum lycopersicum). The study ascertained that the medicarpin content of
the said plant is an effective treatment for fungi. Since
Gliricidia has already proven its power on fungal infections, the researchers conducted
several experimentation and trials to figure out its effectiveness; with this, Anthracnose
can now be prevented and cured without the help of commercially known
anti-fungal treatment.
