Description

Technical Field

[0001] The invention relates to the technical field of plant pest control, in particular to a method for applying pesticide to tree trunks for controlling trunk-boring pests. Background Art

[0002] In landscaping and forestry production, trunk-boring pests are one of the important factors that endanger the health and growth of trees. These pests often hide inside the trunks and damage the tree's conductive tissues by eating the xylem, resulting in stunted growth, weakened tree vigor, and even death. Therefore, preventing and controlling trunk-boring pests has become an important task in protecting forest resources and maintaining ecological balance. Trunk application of pesticides has been widely used in practice as a direct and effective means of prevention and control.

[0003] In the patent entitled "A method for controlling borer pests of macadamia nut trees" and the publication number CN108668741B, it is proposed that borer pests are a general term for borer moths and pseudo-boring moths. Borer pests that harm macadamia nuts mainly include litchi pseudo-boring moth, acacia pseudo-boring moth and coffee leopard borer moth, which feed on the phloem or xylem of branches and trunks with their larvae, weakening the tree vigor. When the damage is serious, it often causes the death of some branches or the whole plant. The use of a combination of multiple drugs to control pests can achieve significant results, but in the process of applying pesticides to the trunks of fruit trees, when applying pesticides once or multiple times, if the number of times of application is too many, the fruit trees may be contaminated by the drugs. Therefore, a method for applying pesticides to the trunks of fruit trees to control borer pests is proposed. Summary of the invention

[0069] S7, focus on rechecking. After 8 days of placing the insect-repellent trees in step S6, focus on rechecking whether new insects and new insect holes appear on the trees that originally had insect holes and insects. When new insect holes and insects appear, release a specified number of natural enemies of pests with mobile marks for prevention and control. Keep track of the operation of the natural enemies of pests within 3 days, and keep following up on the pest situation of the trees. When the pests and diseases disappear, reclaim the natural enemies of pests according to the mobile marks.

[0070] Specifically, in S2, soil physical and chemical factors in the tree trunk area where the pesticide is to be applied are sampled regularly according to the five-point sampling method, and the regular period is 50 days.

[0071] Specifically, in S2, the plant diversity calculation method is dMa=(S-1) / lnN, wherein dMa is the plant Margalef richness index, S represents the population size, and lnN represents the total number of individuals, wherein the rate of stem-boring pests infested plants (%)=number of damaged plants / total number of surveyed plants×100%.

[0072] Specifically, in S3, during the fertilization treatment, for every 100 kg of fertilizer, there are 20 kg of urea, 25 kg of diammonium phosphate, 15 kg of potassium sulfate, 40 kg of decomposed organic fertilizer, 1 kg of wood ash and 10 camphor balls, wherein the camphor balls are placed on the top layer of the fertilizer and the surface is covered with a layer of wood ash again.

[0073] Specifically, the weight ratio of the components of the whitening agent in S4 is: quicklime: 10 parts, water: 40 parts, salt: 2 parts, lime sulfur or sulfur powder: 3 parts.

[0074] Specifically, the insect repellent trees transplanted in S6 include one or more combinations of camphor trees, lemon eucalyptus, mountain pepper trees, lavender, tuberose trees, sweet olive trees, rosemary, sycamore trees, osmanthus trees and lemon balm.

[0075] Specifically, the various insect repellent trees are all young trees within 2 meters, and have grown branches and leaves that emit an insect repellent smell. The various insect repellent trees are placed inside flower pots and transplanted into the forest garden. The flower pots and insect repellent trees are placed 20 cm away from the trees.

[0076] Specifically, in S7, when a designated number of natural enemies of pests with moving marks are released for prevention and control, the number of designated natural enemies of pests is controlled at 5.

[0077] Specifically, in S7, before releasing the natural enemies of the pests to move freely, the pests are lured to one place by focusing the light using a frequency-vibration insecticidal lamp, and the natural enemies of the pests are allowed to eat the pests naturally, so that the natural enemies of the pests will autonomously find the pests for killing after being released.

[0078] Specifically, each vibration insecticidal lamp is placed in a designated location, and the natural enemies of pests are placed at the designated location to be released.

[0079] Furthermore, the present invention is designed to be used in cases where fruit trees encounter insect pests and chemical agents have been used to treat the problem but the situation is not good or cannot be solved. When chemical agents are used multiple times and have no effect, too much chemical agents will penetrate into the fruit trees, causing the accumulation of drugs inside the fruit trees. When a large amount of drugs accumulate inside the fruit trees, it will cause damage to the fruit trees. Therefore, in the present invention, when chemical agents are not effective or have no effect, the present invention can also be used to place multiple insect-repellent trees around the fruit trees. Among the insect-repellent trees, many of the insect-repellent trees are young trees within 1-2 meters, and have grown branches and leaves that emit an insect-repellent smell. Many of the insect-repellent trees are placed in flower pots and transplanted into the forest garden. The flower pots and insect-repellent trees are placed 10 cm away from the trees.

[0080] According to the above technical solution, the working steps of this solution are summarized and sorted out, including the following steps:

[0081] Step 1: First, conduct a detailed survey of plant diversity in the target application area, record the types, number of individuals and trunk coverage of herbaceous plants, and evaluate the ecological environment basis;

[0082] Step 2: Subsequently, the five-point sampling method is used to regularly sample and analyze the soil in the area. The ring knife aluminum box method is used to collect soil samples at a depth of 15 cm to measure its water content and physical and chemical properties, including pH value, EC value, organic matter content, nitrogen, phosphorus, potassium and other element contents, in order to determine the health of the soil and whether fertilization is needed. If the physical and chemical properties of the soil meet the standards, no fertilization is required; otherwise, fertilization treatment is carried out according to the specific situation to optimize the soil environment;

[0083] Step 3: Then, the target tree trunks are carefully inspected by combining regular staggered inspections with fixed-point inspections. Once insect holes or pest threats are found, high-efficiency and low-toxic insecticides are immediately used for local injection, and the tree trunks are quickly painted with whitewash as a mark to facilitate subsequent tracking and observation;

[0084] Step 4: When the pest is more serious, increase the frequency of inspections and conduct focused inspections on the affected trees and their surrounding areas to ensure timely detection and treatment of new pest problems. If the pest is still not effectively controlled after the focused inspections, take ecological prevention measures, that is, transplant trees with insect repellent effects, such as camphor and lemon eucalyptus, to the affected trees and their surrounding areas to use the insect repellent substances they emit naturally to inhibit the growth of pests;

[0085] Step 5: After transplanting, conduct a focused review to evaluate the effect of insect repellent, and if necessary, release natural enemies of pests with mobile markers, such as ladybugs and parasitic wasps, to further control pests. After release, continue to track the operation of natural enemies and the dynamics of tree pests to ensure the control effect, and promptly recover natural enemies after pests and diseases are eliminated to avoid unnecessary impact on the ecology.

[0086] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
