Problems solved by technology

At present, the insecticidal mulch on the market mainly adopts methods such as spraying, coating, and bonding to coat the insecticide on the surface of the mulch (CN201120069305.X). The effect is difficult to be guaranteed; Secondly, many similar herbicides and polymer resins or modified polymer resins are prepared into masterbatches in the market, and then the prepared masterbatches are added to the polymer resin and blown into mulch (CN1260115A, CN102898714A, CN201310459993. 4), the mulch film prepared by this method requires that the active ingredients must have high temperature chemical stability, and at the same time, a large number of polymer resin materials are "wrapped", so that the active ingredients in the film cannot be released, or it is difficult to release, and the prevention and control effect cannot be achieved. Effect
Secondly, the use of resin materials does not meet the photosynthetic stability and environmental protection requirements of active ingredients, which affects the application and promotion of mulch

Abstract

The invention discloses an insect-prevention medical membrane. The insect-prevention medical membrane contains the following components by weight percent: 0.01%-2.0% of an insecticide and 0.5%-20.0% of a photolysis-resistant agent. The prepared insect-prevention medical membrane contains 0.01%-2.0% of the insecticide, the 7-day photolysis rate is less than or equal to 5%, the pesticide effect is uniformly released, the prevention effect of the medical membrane to sugarcane moth borers is 70% or above, the control period of validity to stem borers is over 60 days, and the unit yield unit yieldof sugarcane can be remarkably increased by 10%-15%.

Description

technical field [0001] The invention relates to a medicinal film and a preparation method thereof, in particular to an anti-insect medicinal film and a preparation method thereof. Background technique [0002] Sugarcane borers are commonly known as sugarcane borers. Common species include the yellow borer (Aryroploceschistaceana), the bar borer (Chilo venosatus) and the two-spotted borer (C. infuscatellus) of the leaf roller family. Commonly known as sugarcane borer. A common and serious type of pest that damages sugarcane, causing damage to sugarcane seedlings and cane stems with larvae. Invade the growth point at the seedling stage of sugarcane, resulting in dead seedlings; invade the stem of sugarcane in the middle and late stages of growth, causing wormhole nodes, destroying the tissue of the cane stem, reducing the sucrose content, and prone to wind-broken stems or dead shoots, reducing yield . Sugarcane elongation period caused by insect damage "dead tail sugarcane...
