Method for preventing and controlling sugarcane borers by using silkworm excrement

Abstract

The invention discloses a method for preventing and controlling sugarcane borers by using silkworm excrement. The method comprises the following steps: (1) disinfecting and sterilizing; (2) collectingthe silkworm excrement; (3) performing retting fermentation: transporting the treated silkworm excrement obtained in step (2) to into a silkworm excrement tank, composting the silkworm excrement, andcovering the surface of the silkworm excrement with Ramulus mori powder or rice bran during the compositing of the silkworm excrement in order to achieve retting fermentation; and (4) applying: applying the fermented silkworm obtained in step (3) to sugarcane plantation in the following two ways: A, applying the fermented silkworm obtained in step (3) to sugarcane seed stems as a base fertilizerwhen applied to newly planted sugarcanes, and fattening the sugarcanes with a silkworm excrement bioorganic fertilizer; and B, broadcasting the fermented silkworm obtained in step (3) between lines asa spring fertilizer when applied to stubble sugarcanes, and applying the silkworm excrement bioorganic fertilizer as a stem promoting fertilizer. Compared with traditional methods for preventing andcontrolling s, the method of the invention has the advantages of no toxic or side effects, no pesticide residues, greenness, environmental protection, and remarkable sugarcane borer prevention and control effects, and makes sugarcanes have a worm node ratio of 0, have good growth vigor and many effective stems in the seedling period and have a high germination rate, a high tillering rate, low deadheart rate and a high yield.

Description

technical field [0001] The invention relates to the technical field of borer control, in particular to a method for controlling sugarcane borer with silkworm excrement. Background technique [0002] At present, the method of controlling sugarcane borer generally adopts chemical pesticides to control sugarcane borer. This control method will kill the natural enemies of sugarcane borers, pollute the environment, cause ecological damage, and is not conducive to ecological sustainable development; sugarcane products may also have pesticide residues, endangering human health; and it is labor intensive and costly, and the effect of controlling borers is not high. [0003] In the existing research, the control of stem borers is more and more focused on pollution-free and pesticide residue-free control, such as a method for preventing borer pests published in patent number CN201810114554.2, which combines Trichogramma eggs with Beauveria bassiana spores The powder mixture is releas...

Problems solved by technology

[0004] The present invention overcomes the problems in the prior art of using chemical pesticides to prevent and control sugarcane borers, which pollutes the environment and causes ecological damage, which is not conducive to sustainable ecological development; sugarcane products may also have pesticide residues, which endanger human health; more labor input and high cost are required to prevent and control borers. To solve technical problems such as low effect, provide a method for controlling sugarcane borer with silkworm excrement that is efficient, green, environmentally friendly, reduces input costs, and can improve sugarcane yield and quality
