The ingenious use of plant ash in the control of flower diseases and insect pests

Plant ash can not only supply potassium and other nutrient elements of flowers, but also play a good role in the control of flower diseases and insect pests.

Control of leaf blight

Plant ash, tea cake, sulfur powder 1 kg each, lime 1.5 kg, mashed into powder and mixed evenly, spread 1.5 to 2.5 grams per pot of flowers prone to leaf blight.

Prevention and control of leaf spot

Mix with 3 kg of plant ash and 1 kg of quicklime powder and sprinkle, 40 to 60 grams in each basin, or sifted and sprayed with powder, or sprinkle plant ash separately.

Control of root rot

Plant ash has a good control effect on flower root rot. The specific operation method is to peel off the soil at the root and remove the soil around the rotten root. Scrape off the root bark of the disease, and each plant is covered with 0.5 to 1 kg of plant ash and covered with soil.

Prevention and control of powdery mildew

The flowers with powdery mildew can be 5 to 10 centimeters away from the trunk and the root soil with a depth of 5 to lO centimeters can be removed. Each plant is covered with ash of 0.5 to 3 kilograms, and the ash is covered with thin soil.

Prevention and control of seedling diseases

The flower nursery is prone to blight and anthracnose at the seedling stage. When the humidity is high and the temperature is low, the seedling disease is serious, often a large number of dead seedlings. Plant ash can be used to spread along the ridge, with a dosage of 20 to 25 kg per mu.

Control aphids

Sift the plant ash at the end of the grind, spray the plant ash on the aphids when the dew is not dry in the morning (or sprinkle water first), or shake it with gauze and sprinkle it again every three or five days, 2 to 3 times in a row.

Control of root maggots

When the root maggot is harmful in the flower seedling stage, if it is easy to be damaged by root irrigation with pesticides, 30 to 40 kg of plant ash can be applied per mu in the seedling field. The application method is to spread the plant ash evenly on the border at the seedling stage, and then turn and hoe evenly, so that the ash is fully mixed with the soil. You can also apply plant ash in the ditch before sowing or planting, and then sow or plant.

Control of underground pests

When raising seedlings, the seedling land of bulbous flowers is often harmed by underground pests such as grubs, which can be obviously reduced by using plant ash as base fertilizer or covering seed block with plant ash.
