What should I do if green radish gets worms?
As a common indoor leaf-viewing plant, green radish is often related to insect pests. When white spots are found on the back of leaves or small black worms appear around the plants, mastering the correct pest control method can effectively save plant lives. This article compiles 4 safe and effective pest control solutions, combined with preventive and maintenance skills, to help you create a healthy green plant ecology. 1. Practical Guidelines for Natural Insect-Insecting Agents 1.1 Garlicin made from Garlic Insecting Solution has strong insect repellent properties and can kill common pests such as aphids and red spiders. Take 3-4 fresh garlic cloves and mash them into mud, soak them in water at a ratio of 1:20 for 24 hours, filter out the clear liquid and place it into a spray bottle. It is recommended to spray leaf surfaces and soil surfaces in the morning, focusing on the folds on the back of the leaves where eggs gather. Treat it twice a week for 3 weeks to eradicate pests. Pay attention to ventilation and odor dispersion. 1.2 The components of the Soy Water Insect Control Scheme (Y-J) have significant effects on scale insects and thrips. Collect 5-6 cigarette butts or equal amounts of tobacco tobacco, soak them in 300ml of warm water for 8 hours, and filter. Add 2 drops of detergent to enhance adhesion, put it into a spray can, and spray it to focus on pest areas. It is recommended to use cotton swabs to physically remove stubborn insects and wear gloves to avoid contact with nicotine residues during handling. 1.3 Washing powder pest control skills Alkaline solution can destroy the waxy layer of insect epidermis and is suitable for aphid control. Prepare the solution at a concentration of 0.3%(3g washing powder/1L water), and add a small amount of alcohol to improve penetration. After spraying, let stand for 2 hours and rinse with clean water to avoid residual damage to the leaves. This method has quick results but short maintenance time, and needs to be repeated every 3 days until the pests disappear. 2. Chemical control precautions When pests break out in large areas, low-toxic pesticides such as imidacloprid can be used. After diluting according to the instructions, the eggs in the soil were treated with the dipping basin method. After application, green radish should be moved to a ventilated place for maintenance and avoid contact with children and pets for 2 weeks. It is recommended to give priority to the use of biological agents such as matrine to not only ensure the pest control effect but also reduce the risk of environmental pollution. 3. The pest prevention and maintenance system regularly wipes both sides of the leaves with a damp cloth to keep the pores smooth; plant ash is applied every month to adjust the soil pH; newly purchased plants need to be isolated and observed for 2 weeks. At high temperatures in summer, place insect sticking boards around flower pots for physical monitoring to control pests in the bud stage.
Through the triple protection strategy of "physical removal + biological control + environmental control", it can not only effectively solve the existing pest problem, but also establish a long-term prevention mechanism to keep green radish in a shiny and green viewing state.
