Earthwork to make flowers and pesticides is actually very simple.

We use some local methods of self-made flower pesticides are actually very practical, both pest prevention and disease treatment, but also not green environmental protection, and easy to obtain materials, easy to operate, we can try to do some.

First, pest control in family flower cultivation, the common pests are aphids, shell insects, whitefly, thrips, leafhoppers, net bugs, ants, red spiders and so on.

(1) the fruit of Ginkgo biloba is put into a mortar and mashed with the same amount of water to filter the original liquid. When in use, the original solution is diluted with water at 1:2 according to the volume ratio, which can control aphids.

(2) Platycladus orientalis will be mashed, soaked in water at 1:5 by weight for 24 hours, and the filtrate can be sprayed directly to control leafhoppers.

(3) adding water according to the weight ratio of peach leaves at 1:6, boiling for 30 minutes, and direct spraying of the filtrate can control aphids and other molluscs.

(4) cut up the old leaves and add water according to the weight ratio of 1 to 5, or soak the pericarp with water at 1:10 for 24 hours, and the filtrate can control aphids.

(5) Pulsatilla pulsatilla washed, chopped and mashed the plant, added water according to the weight ratio at 1:10, soaked for 23 hours, or boiled for half an hour, its filtrate could control aphids, leafhoppers and net bugs.

(6) the stems were washed, chopped and mashed, and water was added according to the weight ratio at 1:5 and soaked for 24 hours. the filtrate could control aphids, leafhoppers and net bugs.

(7) cut up and mash the stems and leaves, add water according to the weight ratio at 1:4, boil for 1 to 2 hours, and spray the filtrate to control aphids and red spiders.

(8) mint mint is chopped and mashed, water is added according to the weight ratio at 1:5 and soaked for 24 hours. The filtrate can control leafhoppers and net bugs.

(9) chili peppers are added with water according to the weight ratio at 1:10, boil for half an hour, and the filtrate is sprayed to control aphids and bugs.

(10) Tobacco leaves are soaked in water at 1:10 by weight, soaked for 24 hours, or boiled for 1 hour, and the filtrate is soaked through the basin soil, which can kill the ants in the basin; or the filtrate is diluted with equal amount of water and a little soap is added to control aphids, red spiders, thrips and leafhoppers.

(11) Zanthoxylum bungeanum was boiled into 5 parts of raw liquid by adding water at 1:10 in weight ratio, and then diluted and sprayed at 1:10 according to capacity ratio, which could control whitefly and aphids.

Second, disease control in family flower cultivation, the common diseases are powdery mildew, rust, gray mold, rot, leaf spot, blight and so on.

(1) Pinus massoniana needles were taken and boiled for 2 hours to make them slightly gelatinous; the filtrate was diluted with water at 1:1 according to the volume ratio to prevent root rot.

(2) the hibiscus hibiscus flower was soaked in water at 1:10 and soaked for 24 hours, and its filtrate could control root rot and blight.

(3) taking ginger, mashing and squeezing juice, and then adding water to dilute spray according to the volume ratio at 1:20 can prevent and cure rot.

(4) take leeks and mash them, add water according to the weight ratio of 1.6 to 10, and then mix well and spray the filtrate to control rust and aphids.

(5) take green onions and mash them, add water according to the weight ratio of 2 to 1.5, filter and spray to prevent white disease and aphids.

(6) mash the garlic, stir the juice well with water at 1:1 by weight, and dilute the juice with water at 1:3 according to the volume ratio. It can control powdery mildew, gray mold, root rot, aphids, red spiders and other molluscs.

III. Other

(1) baking soda (sodium bicarbonate) has the effect of inhibiting fungal growth. Spraying with 0.1% sodium bicarbonate 0.2% baking soda solution can prevent powdery mildew.

(2) taking plant ash, adding water according to the weight ratio at 3:10, soaking for 49 hours, and spraying on plants after clarification can control aphids and gray mold.

(3) mosquito incense lit with mosquito incense containing pyrethroid and placed in flowerpot, then sealed with plastic pot for 50 ~ 60 minutes, can kill red spider.

(4) Wind oil essence diluted 600 ~ 800 times with wind oil essence can control aphids, shell insects, red spiders and so on.

(5) the detergent is mixed with water at a weight ratio of 1 to 150 and sprayed every 5 days for 2 ~ 3 times, which can control aphids, red spiders, scale insects, whitefly and so on.

(6) potassium permanganate uses 0.02% potassium permanganate aqueous solution of 0.03% potassium permanganate, sprayed once every 2 to 3 days, serious spray twice, can prevent and cure powdery mildew.
