The Pest and Disease Control of Patrinia
As a plant with both medicinal and edible uses, Patrinia is often plagued by pests and diseases during the planting process. Scientific control strategies can not only ensure the healthy growth of plants but also reduce the risk of pesticide residues. This article systematically analyzes the entire process of pest and disease control, helping growers establish a scientific management system.
Technical Details of Patrinia Pest and Disease Control
Targeted Pest Control Solutions
Sucking pests (whiteflies/aphids): When spraying with Imidacloprid 1:2000 diluted solution, it is recommended to operate in the early morning when the dew on the leaves has not dried, taking advantage of the insects' morning activity to enhance the contact killing effect. Combined with yellow sticky traps, the amount of pesticide used can be reduced by 30%.
Jumping pests (flea beetles): Use concentric circle spraying method with Fenvalerate emulsion, creating an isolation zone by radiating the application from the center of the plant. Covering with a pest net after application can prevent secondary invasion of adult pests.
Comprehensive Disease Control Measures
(T-J) Disease control: After diluting the Shou Bao Ke emulsion according to the instructions, spray it on the leaves combined with potassium dihydrogen phosphate to enhance disease resistance. Focus on spraying the back of the leaves, with 3 treatments every 7 days as a course. Preventive application before the rainy season yields better results.
Pest and Disease Prevention Management System
Soil Matrix Treatment
Before planting, treat the soil with 50°C steam for 30 minutes continuously, or use a 500-fold solution of carbendazim for disinfection. It is recommended to rotate planting legumes each season to improve soil structure and reduce the incidence of soil-borne diseases.
Intelligent Water Management
Use a drip irrigation system to keep the soil moisture between 60-70%, avoiding waterlogging that can cause root rot. Build a rain shelter during the rainy season to block the path of pathogens carried by rainwater.
Scientific Plant Pruning
Remove the basal old leaves monthly to maintain ventilation and light transmission in the plant. Pruning tools need to be disinfected with 75% alcohol to avoid cross-infection. Timely removal of weeds in the field can destroy the habitats of pests.
Sustainable Planting Management Suggestions
Implement biological control: Introduce natural enemies such as ladybugs and lacewings to control aphid populations. Companion planting with pest-repellent plants like mint and rosemary to form an ecological barrier. Stop using pesticides 15 days before harvest and use a double removal process with flowing water rinsing and baking soda soaking. Establish a planting log to record the occurrence of pests and diseases for optimizing control measures.
