Methods to Control Postharvest Decay and Diseases
Control of Postharvest Anthracnose Using Chitosan and Lemongrass Oil
Abstract
Anthracnose is a postharvest disease of mango caused by the fungus Colletotrichum gleoesporiodes that results in major economic challenges during transportation and storage. It limits mango production in our country especially where high humidity prevails during the cropping season. Symptoms of this postharvest disease are black spots, starting from the stem, then proceeding to infect the mango fruit itself. For the control of mango anthracnose, antifungal effects of chitosan, lemongrass oil and the combination of both were examined in vitro. The investigatory project’s objective is to test the effectiveness of Lemongrass Oil and Chitosan to control postharvest anthracnose and also aims to compare its effects and develop new methods to constrain it.
Following the protocol, the proponents were able to conduct three trials of the said protocol. The most effective control method for regulating the anthracnose activity in mangoes is chitosan, the exoskeleton of shrimp. The researchers believe this is effective, due to the results that state that the experimental setups, with chitosan applied, did not change, which means that chitosan controlled the fungal activity. In the other experimental setups, there were some setups that worsened to the point that worms already manifested in the zone of inhibition, while there are some setups showing progress, but not as a big of a progress as the chitosan used in the experimentation process. Therefore, the researches can conclude that chitosan can be used in mango production to control the anthracnose activity after the mangoes have been harvested.
Areca catechu As Weight Enhancer For Chicks
Abstract
In this investigatory project, the researchers developed another way for chicks to gain weight. The researchers used the decoction of Areca catechu by diluting it in water. The bunga was boiled in 2,288 mL. of water to obtain 5% concentration, 10%
