Using pesticides to prevent flower and tree diseases and insect pests is easy to pollute the environment. Now we will introduce four methods for preventing and controlling flower and plant pests and diseases.
First, spray method
(1) Use 0.5 kg of plant ash to dilute 2.5 kg and soak for 24 hours. Spray the filter to kill the aphids on the plum, rose, and pomegranate trees.
(2) Spraying with a baking soda liquid with a concentration of 0.1% can prevent powdery mildew in roses, chrysanthemums, impatiens, hibiscus, cineraria and other flowers, and the control rate can reach over 80%.
(3) The urea solution with a concentration of 2% is sprayed once every 10 days and sprayed twice to three times to kill locusts, red spiders and other pests on flowers and trees.
Second, rubbed
(1) Wipe the vinegar with a cotton ball and rub lightly on the camellia leaves to kill the scale insects and return the green leaves that had been damaged by the scale insects.
(2) Repeatedly rubbing the orchid leaves with alcohol can remove the above scale insects.
(3) Bonsai bonsai branches are rotted and can be scraped off by rotting on the stump with an iodine-disinfected blade, then rubbed with iodine, and rubbed again once every 7 days to 10 days to prevent further rot. .
Third, fertilization method
(1) Apply a small amount of silicon fertilizer when fertilizing flowers and plants. After absorption, flowers and trees can increase the firmness of their epidermal cells, thereby enhancing the resistance to insect pests.
(2) Frequently weeding wood ash can significantly reduce the incidence of gray mold in flowers such as peony, tulip, and cyclamen, and also play a role in stimulating flower buds and bright colors.
Fourth, injection method
Woody flowers are often jeopardized by insects such as longhorn beetles, giardins, and mottled moths. Severe trees can be hollowed out. In order to prevent and control such insect pests, 20 ml to 20 ml of 20% ammonia in water can be injected into the wormholes at the hatching stage of the larvae, before emergence of the adult larvae, and overwintering of the larvae. Then the wormholes can be sealed with clay or wax to kill. Larvae eggs.
