<P>PROBLEM TO BE SOLVED: To prepare a foam sheet intended for excluding damages by ants, aphids, armyworms, and scale insects and other creatures inhabiting the ground to plants. <P>SOLUTION: This foam sheet has far infrared radiation effect and anion effect which bring ideal dwellings to insects inhabiting the ground. The larvae of noxious insects such as aphids, armyworms and scale insects which give damages to plants adhere to the body and the feet of such insects inhabiting the ground and adhere to stems, trunks and leaves of plants from the ground. The insects do not rise plants by giving ideal dwellings to the insects inhabiting the ground, and this effect prevents the larvae of the noxious insects from adhering to the stems, trunks and leaves of plants. So far it is impossible to prevent invasion of the insects inhabiting the ground, so the larvae of aphids, armyworms and scale insects adhere to plants to invade. The damages by the noxious insects can be avoided by preventing invasion of the insects. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
