Diseases and insect pests of honeysuckle and their control
As a representative of traditional medicinal plants in China, honeysuckle is often threatened by pests and diseases during its growth. These diseases not only affect plant growth, but are also directly related to medicinal value and economic benefits. This paper systematically combs the characteristics of common pests and diseases and control plans during honeysuckle planting to help growers achieve scientific management. Guidelines for honeysuckle pest control carrot microvascular aphids: The fastest-growing threat This pest can reproduce for 20 generations a year, concentrating on harming tender shoots. In addition to spraying 3-5 Baume sulfur mixture to kill eggs, it is recommended to cooperate with physical control: hang yellow sticky insect boards (spacing 5 meters/block), and cooperate with biological control to release ladybugs (3-5 per square meter) to form a three-dimensional prevention and control system. Yumuohorn moth: The use of frequency-vibrating insecticidal lamps (1 lamp per 2 acres) during the emergence period (May to June) of the night-active trunk borers is significant. A new type of root irrigation agent is recommended for larvae control: 30% chlorantraniliprole SC 2000 times solution, combined with tree trunk white (quicklime: sulfur: water =10:1:40) to block the oviposition channel. Comprehensive prevention and control of honeysuckle diseases: Brown spots/white powder/coal pollution disease Brown spots appear in the early stages of the disease, and concentric ring patterns are formed after expansion. In addition to zineb, 25% azoxystrobin SC 1500 times solution can be used alternately. The key to the prevention and control of powdery mildew lies in humidity control. It is recommended to build rain shelters (light transmittance of 70%) and spray 29% Pyronaphthyl Azoxystrobin SC 2000 times solution. The dual strategy of coal pollution disease prevention and control first controls the aphid population, and secondly improves ventilation and light transmission: the "three main branches and six main branches" pruning method is used to maintain a 1.2-meter ventilation zone between plants. Pharmaceutical control recommends 22.5% picoxystrobin SC 1500 times solution + silicone adjuvant to improve leaf attachment rate.
By establishing a pest monitoring and early warning system (setting up 1 monitoring point every 5 acres), combined with the trinity model of agricultural control (selecting disease-resistant varieties), biological control (releasing predatory mites) and chemical control, control costs can be reduced by more than 30%. It is recommended that growers establish a prevention and control log to record in detail the time, concentration and effect of each application to provide data support for precise prevention and control.
