Control prickly sucking pests of flowers and understand the cultivation techniques of edible fungi

Aphids, red spiders and shell insects are the three most common piercing pests that damage flowers and trees. The following simple and effective prevention and control methods are not only convenient to draw materials, but also do not pollute the environment.

Aphids: they occur all the year round. They gather on buds, young leaves or twigs, sucking juice and harming bud cores and petals. Prevention and control methods:

1. Use 50 grams of fresh or red chili peppers, add 30 to 50 grams of water, cook for about half an hour, and spray the damaged plants with its filtrate.

2. Use 3 to 4 grams of washing powder, add 100 grams of water, stir into a solution, spray 2 to 3 times in a row, the control effect is up to 10%.

3. Use "wind oil essence" to add water 600 to 800 times the solution, use the sprayer to spray the pests carefully, so that the insect body is stained with potions. The effect of killing aphids and shell insects and other pests is more than 95%, and will not cause drug damage to the plant.

Red spider: its nymphs often gather on the back of leaves and buds of some flowers, sucking plant sap with prick mouthparts. Prevention and control methods:

1. Soaking citrus peel with water for about 10 times for one day and night, spraying plants after filtration can control aphids and red spiders.

2. 15 grams of washing powder, 15 milliliters of 20% caustic soda and 7.5 kilograms of water were mixed and sprayed. The mortality rates of adults and nymphs of red spiders were 94% and 98%.

3. Light a plate of mosquito-repellent incense, place it in a pot of diseased plants, and tie it tightly with a plastic bag. After smoking for about an hour, both eggs and adults can be killed.

Scale insects: when the shell insects absorb the sap of the plants, the damaged plants will not only grow poorly, but also have yellowing leaves and early defoliation. The real worm is wrapped in a layer of horny carapace, and it is not effective if it is sprayed directly with medicine. Prevention and control methods:

1. The ratio of liquor to water is 1 ∶ 2. When controlling insects, water through the surface of the basin soil. The potion can be poured in the middle of April, and then every half a month or so, four times in a row.

2. Use vinegar (rice vinegar) 50ml, soak small cotton balls in vinegar, gently wipe the stems and leaves of damaged flowers and trees with wet cotton balls, and then wipe off the shell insects.

3. Diesel oil, washing powder and water were mixed into mother liquor at the ratio of 10 ∶ 0.6 ∶ 6. At this time, the mother liquor was milk-like. After diluted with water, the scale insects on Milan, kumquat and cycad were carefully sprayed. A week later, most of the scale insects changed from fresh orange to withered. Source: Jingjiao Daily)
