The invention provides a method for preparing an environmentally-friendly
insect-preventing material and relates to a novel environmentally-friendly
insect-preventing material based on
plant composition and a preparation method thereof. The method comprises the following steps: rapidly
drying and smashing fresh rhizomes, leaves, peels and seeds of a specific regenerating
plant with a
drug action, and preparing the dried and smashed substances according to a scientific ratio into a
raw material; and integrating the
raw material with other solidified materials by using a specific process and a slow-releasing technique, thus the active ingredients are released slowly and lastingly. The preparation process is simple and convenient, the
raw material is easily available, the cost is low, the raw material can be industrially planted, and a novel occupation ideal of 'material farmer' is established. The
insect-preventing material is safe to humans and animals, is ecologically environmentally-friendly and has a broad-spectrum parasite-expelling function, a long-acting
drug action and an excellent effect. The insects hardly generate the resistance to drugs while the
natural enemies of the insects are not hurt. By applying the environmentally-friendly insect-preventing material to the fields of
agriculture and
forestry, the damages to the living and growing capabilities of animals and plants caused by the
plant diseases and insect pests are prevented, the environmentally-friendly organic food is produced, the environmental
pollution problem caused by applying a large number of chemical pesticides is avoided, the
food safety is strictly controlled from the source, the quality of agricultural products is increased, and the income of the famer is also increased.
