PROBLEM TO BE SOLVED: To provide an agrochemical-free transparent high polymer film for the physical isolation of disease and insect damage which has low cost, can be used repeatedly, and can prevent the disease and insect damage of plants effectively under the precondition without using agricultural chemicals; and to provide a production method thereof.SOLUTION: An agrochemical-free transparent high polymer film for the physical isolation of disease and insect damage of the invention is a transparent plastic film with a thickness of 0.03-1.00 mm, wherein pores with a pore size of 1-30 mm and with a densities of 1,000-200,000 holes/mare provided. The agrochemical-free transparent high polymer film for the physical isolation of disease and insect damage can prevent the invasion of disease and insect damage effectively, and even under the condition without using agricultural chemicals, plants can be completely grown in the condition without the invasion of disease and insect damage. The agrochemical-free transparent high polymer film for the physical isolation of disease and insect damage which is used in the invention can be used repeatedly, is easy to handle, and is a low-cost auxiliary tool for farming, as well as enables simple and convenient cultivation without using agricultural chemicals.SELECTED DRAWING: Figure 1 |
