Embodiment 1

[0021] A method of using the trapping plant vetiver to prevent and control the Sorrel borer, the method is to plant the trapping plant Vetiver in the sugarcane orchard to lure the adults of S. and larva poisonous effect to control sugarcane borer. Specifically, on the ridge of the perennial sugarcane garden in irrigated land, vetiver rooted plants are planted along the periphery of the ridge, and the planting density is determined according to the actual situation in the field; Planting without replanting, pruning 1-2 times a year, and cutting off the stems above the ground. The pruning time is in the middle and / or the end of each year, so that the seedling stage of vetiver coincides with the period of high incidence of the large borer. Vetiver can be controlled by herbicides such as glyphosate according to field planting requirements.

Embodiment 2

[0023] A method of using the trapping plant vetiver to prevent and control the Sorrel borer, the method is to plant the trapping plant Vetiver in the sugarcane orchard to lure the adults of S. and larva poisonous effect to control sugarcane borer. Specifically, the vetiver tillering seedlings (the tillering seedlings can be cut off the stalks above the ground) are set in the middle of the newly planted sugarcane sugarcane garden in the paddy field. Vetiver tillering seedlings were planted according to conventional planting methods. The vetiver tiller seedlings are planted in a parallel arrangement, planting a row at intervals of 20-30m, and the distance between holes is 0.5-0.6m. After the vetiver is planted, the perennial roots are planted for a long time without replanting. Pruning is done once a year, and the above-ground stems are cut off evenly with the soil. The vetiver is managed according to the normal water and fertilizer of the sugarcane garden, no special manageme...

Embodiment 3

[0025] A method of using the trapping plant vetiver to prevent and control the Sorrel borer, the method is to plant the trapping plant Vetiver in the sugarcane orchard to lure the adults of S. and larva poisonous effect to control sugarcane borer. Specifically, the vetiver tillering seedlings are set in the perennial cane orchard in the dry land. Vetiver tiller seedlings are soaked in normal temperature water for 1-2 hours before planting. The vetiver tiller seedlings are planted in a parallel arrangement, planting a row at intervals of 30-50m, and the distance between holes is 0.6-1.0m. After the vetiver is planted, the long-term perennial roots are planted without replanting. Pruning is done twice a year, and the stems and stems on the ground are cut off evenly. Grass can be divided into seedlings or transplanted according to the density of the field, and herbicides such as glyphosate can also be selected for control according to the layout of the field.

Abstract

The invention discloses a method of utilizing a trap plant-vetiver to prevent and control sesamia inferens in a sugarcane garden. The method includes that the trap plant-vetiver is planted in the sugarcane garden to induce adult sesamia inferens to lay eggs, and effects of vetiver on trapping adult sesamia inferens and poisoning larvi are utilized to prevent and control sesamia inferens in the sugarcane garden. Vetiver which is a host plant that sesamia inferens likes to eat is planted in the sugarcane garden at proper time to give play to effects of vetiver on trapping and poisoning sesamia inferens, and sesamia inferens is induced onto vetiver to be prevented and controlled in a centralized manner, so that population number of sesamia inferens in the sugarcane garden is reduced effectively, direct damage of sesamia inferens to sugarcane is reduced, good sugarcane garden ecology can be built, pest natural enemy reproduction is promoted, natural control force of natural enemy is improved, and the objective of effectively controlling sesamia inferens for a long time is achieved.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a method for preventing and controlling the cane orchard borer by using the trapping plant vetiver. Background technique [0002] The large borer (Sesamia inferens Walker) belongs to Lepidoptera, Noctuidae, and is an important borer pest on sugarcane. The large borer harms sugarcane with larvae, and it is harmful throughout the growth period of sugarcane. In the seedling stage, it damages the growth point of sugarcane seedlings and causes dead seedlings, reducing the number of effective seedlings in the field; in the middle and late stages of growth, it damages the cane stem, destroys the tissue of the cane stem, hinders the growth of sugarcane, and reduces the yield and sucrose content. According to investigations, the heart rate of sugarcane seedling borer damage is generally 10% to 20%, and the serious one is 70% to 80%. After the sugarcane is damaged, the yield will be...
