Techniques for the Control of Diseases and Pests in Honeysuckle
Common diseases in honeysuckle cultivation include brown spot and powdery mildew, while the main pests are aphids, inchworms, and longicorn beetles. When diseases and pests occur, it is necessary to cut off the diseased leaves, handle the diseased and damaged plants, and spray pesticides. Generally, spraying can resolve pest infestations. For controlling inchworms, dig the soil within 1 meter around the plants after spring to destroy the pupae. In the early stage, you can spray pesticides to kill them. For longicorn beetles, when insect-infested branches are found, cut them off and burn them. If there are wormholes, plug them with cotton soaked in 80% dichlorvos solution and seal with soil to kill the larvae.
Common Diseases in Honeysuckle Cultivation
Brown spot is a common leaf disease that causes the plant to weaken. It often occurs in the later growth stage, with August and September being the peak period of the disease, particularly in rainy and humid conditions. Initially, brown spots appear on the leaves, which then expand into brown circular or irregular spots. The back of the spots may have gray-black moldy matter. Severe cases can cause leaf drop. Powdery mildew occurs严重 in warm and dry conditions or when the plants are shaded; excessive application of nitrogen, dense plant growth, can also exacerbate the disease. Initially, white spots appear on the leaves, which gradually expand into white powdery patches, covering the entire leaf and causing yellowing, wrinkling, deformation, and eventually leading to flower and leaf drop, as well as dried branches.Major Pests in Honeysuckle Cultivation
1. Aphids: They harm the leaves and young branches, causing curling of leaves and buds, stopping growth, and significantly reducing yield. The situation is more severe from April to June, especially around the "Start of Summer" and particularly in rainy days.2. Inchworms: After the flowers bloom, the larvae consume the leaves, causing yield reduction.
3. Longicorn Beetles: After the plants are attacked, they gradually wither and die.
Techniques and Management Methods for the Control of Diseases and Pests in Honeysuckle
For brown spot, cut off the diseased leaves and then spray a Bordeaux mixture in a 1:1.5:200 ratio, once every 7-10 days, for 2-3 consecutive times; or use a 65% zinc omethoate solution diluted 500 times or a 1000-1500 times diluted thiophanate-methyl solution, spraying once every 7 days for 2-3 consecutive times. For powdery mildew, clean the garden of diseased and damaged plants; during the occurrence period, use a 50% thiophanate-methyl solution diluted 1000 times or a BO-10 biological preparation spray. For aphids, use a 40% dimethoate solution diluted 1000-1500 times or a 1000-1500 times diluted灭蚜松 (灭蚜灵) solution to spray and kill, repeating multiple times until they are eliminated. For controlling inchworms, dig the soil within 1 meter around the plants after spring to destroy the pupae. In the early stage of larval occurrence, spray a 2.5% karate emulsion diluted 400-600 times; or use dichlorvos or other pesticides for spraying, but stop spraying during the flowering period. For longicorn beetles, when the adult beetles emerge from the soil, pour an 80% trichlorfon solution diluted 1000 times into the flower墩. During the peak egg-laying period, spray an 80% trichlorfon crystal solution diluted 800-1000 times once every 7-10 days; when insect-infested branches are found, cut them off and burn them; if there are wormholes, plug them with cotton soaked in 80% dichlorvos solution and seal with soil to kill the larvae.The above sharing of specific introductions to the techniques for the control of diseases and pests in honeysuckle is hoped to be liked by everyone!
