How to effectively use plant ash to control plant diseases and insect pests?

How to use plant ash to control plant diseases and insect pests? To know that the use of pollution-free, low-cost, simple plant ash has a significant effect on the control of flower and plant diseases and insect pests. Below, the editor of Huinong Network has summarized several common flower and plant diseases and insect pests how to use plant ash control methods!

I. 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 disease

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

Prevention and control of root rot

Plant ash has a good control effect on flower root rot. The specific operation methods are as follows: first peel off the root soil and remove the soil around the rotten roots; scrape off the diseased root bark, and each plant is covered with 0.5 to 1 kg of plant ash, which is covered with soil.

Fourth, prevention and control of powdery mildew

For flowers with powdery mildew, 5 to 10 centimeters away from the trunk, remove the root soil with a depth of 5 to 10 centimeters, cover 0.5 to 3 kilograms of plant ash, and cover the ash with thin soil.

5. Prevention and control of harm at seedling stage

Flower nursery is easy to occur blight, anthracnose and so on in the seedling stage, when the humidity is high and the temperature is low, the seedling disease occurs seriously, often a large number of dead seedlings, can be spread with plant ash along the ridge, the dosage per mu is 20 to 25 kg.

VI. Control of aphids

Grind and screen the plant ash, 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.

7. Control root maggots

In the flower seedling stage root maggot harm, such as the use of pesticides root control easy to occur drug damage, you can apply 30 to 40 kg of plant ash in the nursery. 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 can be fully mixed with the soil; it can also be applied in the ditch before sowing or planting, and then sowing or planting.

VIII. 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.

About how to use plant ash to treat plant diseases and insect pests skillfully, the editor of Huinong Network has introduced this for you. If you want to know more about flowers and plants, please continue to pay attention to Huinong Network of this site!

Using plant ash to control diseases and insect pests of flowers and trees

Plant ash: is the residue of plants after burning. Because plant ash is the ash of plants after burning, almost all the mineral elements contained in plants are contained in plant ash. Among them, the highest content is potassium, which generally contains 6% to 12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate, followed by phosphorus, which generally contains 1.5% to 3%. It also contains calcium, magnesium, silicon, sulfur and micronutrient elements such as iron, manganese, copper, zinc, boron and molybdenum.

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

1. 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.

two。 Prevention and treatment of leaf spot: mix with 3 kg of plant ash and 1 kg of quicklime powder, 40 to 60 grams in each basin, or sifted and sprayed with powder, or sprinkle plant ash alone.

3. Prevention and control of root rot: plant ash has a good control effect on flower root rot. The specific method of operation is as follows: first peel off the soil of the root, and remove the soil around the rotten root; scrape off the skin of the diseased root, and cover the root with 0.5 to 1 kg of plant ash, which is covered with soil.

4. Prevention and control of powdery mildew: the flowers with powdery mildew can be 5 to 10 centimeters away from the trunk, remove the root soil with a depth of 5 to 10 centimeters, cover 0.5 to 3 kilograms of plant ash, and cover the ash with thin soil.

5. Prevention and control of seedling diseases: flower nursery is prone to vertical blight and anthracnose at seedling stage. When humidity is high and temperature is low, seedling disease occurs seriously, often a large number of dead seedlings, can be spread with plant ash along the ridge, the dosage per mu is 20 to 25 kg.

6. Control aphids: sift the plant ash, spray the plant ash on the aphids when the dew is not dry (or sprinkle water first) in the early morning, or shake it with gauze and sprinkle it again every three or five days, 2 to 3 times in a row.

7. Prevention and control of root maggots: when root maggots are harmed 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 can be fully mixed with the soil; it can also be applied in the ditch before sowing or planting, and then sowing or planting.

8. Control of underground pests: when raising seedlings, bulbous flower seedlings are often harmed by grubs and other underground pests, which can be obviously reduced by using plant ash as base fertilizer or covering seed blocks with plant ash.
