Methods of using worm castings for fungal control 


Abstract
The present invention describes a material and a method for 
controlling fungi. The method consists of disposing a naturally 
formed chitinase about an area to be protected. The naturally formed 
chitinase is produced from worm castings and the worm castings may be 
disposed naturally, in the form of timed-release pellets, or in a 
liquid form. The area to be protected includes plants and structures. 
The naturally formed chitinase may be disposed about the base of the 
plant or structure, or on the leaves of the plant.

Methods of using worm castings for insect repellency 


Abstract
Worm Castings are the feces or excrement from the common red 
earthworm found in much of the world. Worm castings are produced as a 
normal part of the worm life cycle when worms are fed a diet of 
various forms of biodegradable materials such as compost, paper, food 
waste, and any other organic material, which will degrade. The genus 
of the most common worm is eisenia foetida. Other earthworms are 
available and also provide worm castings, which can be used for this 
invention. These worm castings contain enzymes known as various forms 
of chitinase of which insects have a strong aversion. When the worm 
castings are put in a layer, walking insects such as ants won't cross 
the layer and ants in nests under the layer will leave the nests to 
get away from the worm castings. The worm castings also have the 
ability to activate multiplication of the chitinase-producing 
bacteria found naturally in plants. The concentration of chitinase 
must be sufficiently high to repel insects. Testing has shown that 
the natural level of chitinase found in most plants is not sufficient 
to repel insects. The level of chitinase is multiplied to a repulsion 
level with the use of worm castings. Liquid worm castings can be used 
as a foliar spray to administer a concentration of chitinase 
topically to the leaves and stems of plants. Liquid worm castings 
give a temporary repellency effect that can be effective to keep the 
insects away until the level of natural repellency is increased in 
the nectar of the plant. Worm castings can also be added to the 
hydroponic feed liquid for plants to provide sufficient level of 
chitinase to repel insects.
