How to prevent and control diseases and insect pests such as flower leaf blight, powdery mildew and root rot.

Prevention and control of leaf blight: plant ash, tea cake, sulfur powder each 1 kg, lime 1.5 kg, crushed into powder after mixing evenly, easy to occur leaf blight flowers per pot spread 1.5 to 2.5 grams.

Control leaf spot disease: plant ash 3 kg, quicklime powder 1 kg mixed evenly after spreading, 40 to 60 grams per pot, or sieving powder, or scattered plant ash alone.

Control root rot: plant ash has a good control effect on flower root rot. The specific method of operation is to first remove the soil at the root and remove the soil around the rotten root. Scrape the diseased root bark and apply 0.5 to 1 kg of plant ash to cover the roots and cover them with soil.

Powdery mildew control: the occurrence of powdery mildew flowers can be 5 to 10 cm away from the trunk, remove 5 to 10 cm deep root soil, 0.5 to 3 kg of plant ash per plant cover, ash covered with thin soil.

Prevention and control of seedling diseases: flower nursery seedling easy to occur blight, anthracnose, etc., in the humidity, low temperature, seedling disease occurs heavily, often a large number of dead seedlings. Available plant ash along the ridge, mu dosage of 20 to 25 kg.

Control aphids: grind plant ash and sieve it. Spray plant ash on aphids when dew is not dry in the morning (or sprinkle water first). It can also be sprinkled with gauze. Sprinkle it once every three or five days. Sprinkle it 2 to 3 times in a row.

Control root maggots: in the flower seedling root maggots harm, such as root irrigation with pesticides easy to occur phytotoxicity, can be applied in the seedling mu 30 to 40 kg plant ash. The method of application is to spread plant ash evenly on the surface of the ridge at the seedling stage, and then hoe evenly to make the ash fully mixed with the soil. Plant ash can also be applied to furrows before sowing or planting, and then sowing or planting.

Control of underground pests: seedling, bulbous flower seedlings often suffer from underground pests such as white grubs harm, with plant ash for base fertilizer control, or plant ash cover seed block, can significantly reduce harm.

Plant ash can not only supply potassium and other nutrients for flowers, but also have a good effect on controlling flower diseases and insect pests. Did you use plant ash.

Prevention and control of leaf blight: plant ash, tea cake, sulfur powder each 1 kg, lime 1.5 kg, crushed into powder after mixing evenly, easy to occur leaf blight flowers per pot spread 1.5 to 2.5 grams.

Control leaf spot disease: plant ash 3 kg, quicklime powder 1 kg mixed evenly after spreading, 40 to 60 grams per pot, or sifting powder, or plant ash alone.

Control root rot: plant ash has a good control effect on flower root rot. The specific method of operation is to remove the soil from the roots and remove the soil around the rotten roots. Scrape the diseased root bark and apply 0.5 to 1 kg of plant ash to cover the roots and cover them with soil.

The method of application is to spread plant ash evenly on the surface of the ridge at the seedling stage, and then hoe evenly to make the ash fully mixed with the soil. Plant ash can also be applied to the ditch before sowing or planting, and then sowing or planting.

Prevention and control of underground pests: seedling, bulbous flower seedlings often suffer from grubs and so on.
