What medicine to use for gardenia pest control
The white and fragrant gardenia is a common ornamental plant in the courtyard, but the sudden appearance of pests on the leaves always makes flower growers worried. How should we scientifically prevent and control the common pest problems of gardenias? This article will systematically analyze the complete plan for pest treatment and prevention.
I. Common Gardenia Pest Control Methods
1. Aphid Infestation Treatment Plan
Aphids gather on the tender buds to absorb sap, causing the leaves to curl and deform. In the early stage, they can be removed one by one with a cotton swab dipped in alcohol. When the pest population is dense, it is recommended to use a 10% imidacloprid wettable powder 2000 times solution. Folk remedies include using a cigarette butt soak (10 cigarette butts/500ml water) sprayed weekly, taking care to avoid the strong sunlight period at noon.
2. Scale Insect Eradication Techniques
This type of pest adheres to the branches and secretes sticky fluid, which can be physically removed with a soft brush dipped in 75% alcohol. The recommended chemical control is a 20# petroleum emulsion 200 times solution, ensuring that the spray covers the back of the leaves' gaps, with a better effect after consecutive use for 3 times at 7-day intervals.
3. Strategy for Dealing with Caterpillar Larvae
This type of leaf-eating pest can be treated with a precise spray of 2.5% brom** ester emulsion 3000 times solution, focusing on the back of the leaves. Biological control can introduce Trichogramma, which is an effective natural enemy to control the population of caterpillars.
II. Pest Prevention and Management System
Regularly prune dense branches to maintain ventilation, and apply ripe cake fertilizer monthly to enhance resistance. Spray 1% Bordeaux mixture before the plum rain season to prevent diseases, and thoroughly clean up the fallen leaves and branches during the winter clean-up. Covering the surface of the pot soil with diatomite can form a physical pest control layer.
When unknown pests are found, they can first be tested and controlled with a 3% brine solution. If the effect is not good, switch to a broad-spectrum insecticide such as Bai Chong Ling. Daily maintenance should pay attention to hidden parts such as the back of the leaves and tender shoots, early detection and early treatment can minimize losses.
