Control Methods for Orchid Pests and Edible Mushroom Diseases

Aphid control: Use 5 grams of laundry detergent, mix with 1200 grams of water, stir thoroughly and spray, once every 3 days, for 2-3 consecutive times, the insect kill rate can reach 100%.

Snail control: Pour beer into a shallow dish, place it on the ground and on the potting soil. When snails smell the beer aroma, they will crawl into the dish and drown.

Ant control: Crush garlic cloves, dig 3-4 holes in the flower pot, and bury them in the potting soil. After 2-3 days, ants, earthworms and nematodes in the potting soil will be eliminated.

Red spider mite control: Light a mosquito coil containing pyrethrum, place it in the orchid pot, then seal the entire pot with a plastic cover, and smoke for 1 hour to kill egg clusters and adult mites.

Scale insect control: Soak 1 jin of ripe neem tree fruit in 1 kg of water for over 1 month, then take the liquid for use. In late spring and early summer, use a 1:1000 ratio for prevention; if small scale insects are found, use a 1:500 ratio to kill them, once every 5 days, for 3 consecutive times, and the small scale insects can be eliminated.

Tobacco:

Efficacy: Nicotine and nicotinic alkaloids in cigarettes can control pests such as aphids, red spider mites, stink bugs, and ants.

Preparation:

① 40g of crude tobacco leaves or tobacco stems, add 1000ml of water, soak for 24 hours, filter and then add an equal amount of water to dilute, then add 2-3g of laundry detergent to dissolve (if using cut tobacco, the concentration can be higher; adding laundry detergent both helps adhesion and also has insecticidal effects);

② If there is no weighing device, you can soak several de-papered cigarette butts in about 30 times their volume of water, wait until the water turns yellowish-brown, then add a small amount of laundry detergent to dissolve; Usage: use after filtering.

③ Spray the front and back of leaves;

④ When the pest infestation is severe, immerse the affected parts of the flower in tobacco water for 1-3 hours, and also soak the planting medium, which can effectively kill pests on the leaves and in the soil;

⑤ The remaining tobacco water can be poured into ant nests or sprinkled around the pot to eliminate ants;

⑥ Unsoaked cigarette butts buried in the soil can control small flying insects.

Precautions:

① Contains nicotine, do not add vinegar, otherwise it will weaken the insecticidal effectiveness;

② If laundry detergent is added, rinse with clean water on the day after spraying (or immediately after soaking);

③ If mainly used for scale insect control, it is best to add laundry detergent, or use laundry detergent alone.

Garlic:

Efficacy: Can control aphids, red spider mites, scale insects, nematodes and other pests, and can also control powdery mildew.

Preparation:

Take several cloves of purple-skinned garlic from northern China, peel and mash them, add 10-20 times the amount of water to dilute, and filter out the residue after 24 hours.
