How should I prevent and treat pests on fuchsia?
The main pest affecting fuchsia is the red spider mite. The best prevention and treatment method is to place the plant in a well-ventilated spot and spray-wash the entire plant with a strong jet of water, especially the undersides of the leaves. This is caused by dry indoor air; the eggs hatch into adults in a suitable environment and directly harm the plant, but mites are all afraid of moisture, so frequent water spraying can solve it.
If spray-washing is too slow, just spray pesticide directly on the leaf surface. You can choose acaricides such as dicofol and abamectin, diluted about 1000 times. When spraying, be thorough, careful and detailed, and if it rains within 12 hours after spraying, spray again.
In the prevention and treatment of common pests and diseases of the peace lily (Spathiphyllum), the most common pests are aphids, whiteflies, thrips and so on. What should we do when the peace lily we grow gets pests? It is especially important to distinguish the type of pest, take effective pest control measures, and pay attention to later care.
1. Aphids
Symptoms: Aphids are also called greasy bugs or honey bugs, with a body length of about 1.5-4.9 mm, usually 2 mm. They suck sap through their needle-like mouthparts, causing the stems and leaves of the peace lily to curl and wither, and they often appear in spring and autumn.
Prevention and treatment measures: (1) You can use a brush to remove the aphids; if severe, you need to cut off the branches and leaves; (2) You can spray with a 50% malathion emulsion diluted to a 100-fold solution; (3) Carry out later care according to the peace lily cultivation methods and precautions.
2. Whiteflies
Symptoms: Whiteflies are pests with black, red or pale yellow wings, generally no more than 3 mm in body length. They are one of the most harmful pests in the prevention and treatment of common pests and diseases of the peace lily. Their body is oval or nearly round. After sucking the sap of the peace lily, they will cause it to weaken and even die.
Prevention and treatment measures: (1) Remove the whiteflies, using a brush or wooden stick; (2) You can use a high-temperature sealing method, for example, control the temperature at 45-48 degrees and the humidity above 90%, and after 2 hours the whiteflies will basically die; (3) Usually pay attention not to apply too much fertilizer, and the environment should be well ventilated.
3. Thrips
Symptoms: A pest that is yellow, brown or black, with a body length of about 2 mm. It sucks the sap of the plant's young tissues, especially tender leaves and new buds, which will cause the peace lily to curl and wither, causing serious harm.
Prevention and treatment measures: (1) Strengthen the management of fertilizer and water, which can promote the peace lily to grow more robustly and reduce the probability of thrips appearing; (2) Use 25% thiamethoxam water-dispersible granules diluted to a 5000-fold solution for root drenching; (3) Strengthen later care.
Common diseases of the peace lily
1. Leaf spot disease
Symptoms: Leaf spot disease is the most common in the prevention and treatment of common pests and diseases of the peace lily. Oval or elongated light reddish-brown spots appear on the leaves, surrounded by chlorotic rings, which later expand into irregular large patches, and black spots form on the diseased areas.
Prevention and treatment measures: (1) Cut off the diseased tissue and burn it in a centralized manner; (2) Spray with 38% oxadixyl and cymoxanil and copper fungicide diluted to a 1000-fold solution, or spray with 70% mancozeb diluted to a 500-fold solution.
2. Brown spot disease
Symptoms: The disease starts on the lower leaves and then spreads upward. At first it is round or oval, showing purple-brown spots, then turns black, and finally the leaves wither, yellow and fall off, and the peace lily will fail to bloom.
Prevention and treatment measures: (1) In hot and humid weather, apply less nitrogen fertilizer, maintain a certain amount of phosphorus and potassium fertilizer, and avoid watering in the evening; (2) In the early stage of the disease, spray with mancozeb diluted to an 800-fold solution, once every 5 days, 3-4 times is enough to prevent the disease from spreading.
3. Anthracnose
Symptoms: At first, water-soaked light green lesions appear at the leaf tips or leaf edges, then spread along the leaf veins into translucent irregular lesions, and finally change from brown to grayish blue-green.
Prevention and treatment measures: (1) Remove the diseased leaves; (2) Spray with 50% benomyl wettable powder diluted to a 1500-fold solution, or spray with 25% carbendazim wettable powder diluted to a 600-fold solution.
