Techniques and Methods for the Control of Plant Diseases and Pests
In this article, we will share some small green plant maintenance experiences on the techniques and methods for the control of plant diseases and pests. Let's delve into the details below.
Techniques and Methods for the Control of Plant Diseases and Pests
Timely removal of diseased leaves, applying phosphorus and potassium fertilizers to enhance disease resistance, if there are scale insect eggs on the branches, immediately scrape them clean with bamboo chips. For a small number of pests, manual capture can be used. For bags虫, remove the虫囊, extract the adult insects to feed chickens, or spray with a 90% crystalline diazinon solution diluted 1000-1500 times. If leaf mites appear, spray with dimethoate emulsion, and for cottony scale insects, use fenitrothion emulsion.
Common Diseases in Flowering Plant Cultivation
1. The harm of leaf spot disease: Caused by fungi, it includes black spot, brown spot, and red spot diseases, commonly occurring on leaves and fruits. Spots often appear with a mold layer or small black dots, and the affected area dies in the later stage.
2. The harm of powdery mildew: Caused by powdery mildew fungi, it often occurs on leaves, young fruits, and tender branches. Plants like roses and dahlias are prone to this disease.
Major Pests in Flowering Plant Cultivation
1. The harm of aphids: Aphids are light yellow, very small, and concentrate on the back of leaves, affecting almost all flowering plants.
2. The harm of inchworms: They specifically eat the leaves of plants like pomegranates and euonymus. They consume leaves quickly, starting with the top tender leaves and then moving to the lower leaves, capable of defoliating a small pomegranate plant in 12 days, severely affecting the plant's appearance and growth.
3. The harm of bagworms: These pests have a broader range of damage. In the hot and dry weather of early to mid-June each year, they are particularly rampant. Bagworm larvae have strong vitality and can survive without food for 10 days, hiding in their虫囊s during winter.
4. The harm of leaf mites: They commonly affect azaleas, junipers, kumquats, and dragon cypresses, with severe damage to azaleas and junipers. They hide on the back of leaves to suck sap, causing the leaves to turn yellow and eventually fall off. They have a high reproductive rate and thrive in hot and humid environments.
5. The harm of吹绵介壳虫: This pest often affects plants like roses, raspberries, and pine trees, focusing on branches, fruit stems, and other parts, potentially leading to the death of the entire plant.
Control of Plant Diseases and Pests
1. Remove withered branches and leaves promptly and enhance disease resistance by applying phosphorus and potassium fertilizers. If there are scale insect eggs on the branches, immediately scrape them clean with bamboo chips. If the plant grows poorly despite normal fertilization and watering, check for pests in the soil.
2. If there are aphids, soak cigarette butts in water for 24 hours, slightly knead them, filter out the residue with gauze, and then spray. For a small number of caterpillars, manual capture can be effective within half a day. For bagworms, remove the虫囊, extract the adult insects to feed chickens, or spray with a 90% crystalline diazinon solution diluted 1000-1500 times.
3. If there are leaf mites, remove weeds in the pot to eliminate overwintering eggs. When the disease occurs, spray with dimethoate emulsion. For cottony scale insects, spray with a fenitrothion emulsion diluted 1000 times, and promptly remove diseased leaves.
The above is a method introduction on the techniques and methods for the control of plant diseases and pests, which can be used as a reference suggestion.
