How much do Agastache rugosa seeds cost? Detailed planting methods

Agastache rugosa, also known as Hexiang, Canggao, Shanhuixiang, etc., is a perennial herbaceous plant of the genus Agastache in the Lamiaceae family. It is widely distributed throughout China, with main production areas in Sichuan, Jiangsu, Zhejiang, Hunan, Guangdong and other places. As a medicinal herb, it has effects such as resolving dampness and invigorating the spleen, dispelling turbidity and harmonizing the middle, and relieving summer heat and promoting sweating. Now let us take a look at Agastache rugosa seed prices and planting methods!

How much does one jin of Agastache rugosa seeds cost?

The price of Agastache rugosa seeds is about 150-180 yuan per jin, but prices vary greatly depending on seed quality, variety, place of origin and market conditions. Agastache rugosa is mostly propagated by seed. Seeds remain viable for 2-4 years, so seeds from the previous year can be sown. Seed germination requires light conditions, the suitable germination temperature is 18-22 degrees C, and germination takes 7-10 days. Sown in the same year and harvested in the same year, it is called new Agastache rugosa, with many leaves and good leaf quality. In production it can also be propagated by perennial roots (old Agastache rugosa).

Sowing methods for Agastache rugosa seeds

1. Sowing time: In the north, Agastache rugosa is sown in spring, with seedlings raised in mid-to-late April. Before sowing, apply 2.5-3 kg of decomposed human and livestock manure water per sq m to the seedbed, moisten the bed surface as base fertilizer, level and rake fine, then sow.

2. Sowing method: Agastache rugosa can be broadcast sown or drilled. Use 2-4 g per sq m, and 500-800 g of seed per mu of field. Finally, cover the bed surface with plastic film to keep warm and retain moisture.

(1) Broadcast sowing: Mix the seeds with fine sand or plant ash, evenly scatter them on the bed surface, gently pat the bed surface with a thin board so that the seeds make close contact with the bed surface, and cover with 1 cm of soil.

(2) Drilling: Along the bed, open shallow furrows at a row spacing of 25-30 cm, with a furrow depth of 1-1.5 cm. Water thoroughly, mix the seeds with fine sand and evenly scatter them into the furrows, cover with 1 cm of soil, and press lightly.

Planting methods for Agastache rugosa

1. Thinning and filling in seedlings: After sowing Agastache rugosa, when the temperature is 13-18 degrees C and soil moisture is suitable, seedlings emerge in 10-12 days. When seedlings are 10-12 cm tall, thin them, removing the weak and keeping the strong. For drilling, seedlings can be fixed at a plant spacing of 10-12 cm, with two rows staggered. For hole sowing, keep 3-4 strong seedlings per hole.

2. Timely transplanting: When Agastache rugosa seedlings are 12-15 cm tall and have 4-6 true leaves, transplant at a plant spacing of 25 cm and row spacing of 40 cm, choosing an overcast day and watering with thin manure water. Plant 6,000-7,000 plants per mu, and after transplanting water thoroughly to settle the roots. If missing plants are found after they survive, fill them in on an overcast day.

3. Topdressing management: The first topdressing of Agastache rugosa is after loosening the soil when seedlings are 3 cm tall, applying 1.5-2 kg of decomposed thin human and livestock manure water per sq m. After that, apply at seedling heights of 7-10 cm, 15-20 cm and 25-30 cm respectively. Water after fertilizing. Stop topdressing after the rows close.

4. Drainage and drought resistance: Agastache rugosa prefers a slightly moist soil environment. After sowing and transplanting, if drought occurs with no rain, timely watering (irrigation) should be done to protect seedlings against drought. In rainy weather and after irrigation, timely clearing of ditches and drainage should be done to prevent waterlogging, which causes root rot.

5. Timely harvesting: Agastache rugosa is harvested by picking tender stems and leaves and young seedlings from April to June, or at full bloom from July to August. Choose a sunny day and cut it level with the ground, then sun-dry, bake-dry or shade-dry it. Yield is 4,500-7,500 kg per hectare. The best quality is green stems and branches, dry, with many leaves and a rich aroma.

Disease control of Agastache rugosa

1. Root rot

[Damage] It mostly occurs in the rainy summer season. Diseased plants rot from the roots and rhizomes, gradually spreading to the aboveground parts, turning the cortex brown, and finally withering and dying.

[Control] Pull out diseased plants and burn them in a centralized manner, then spread lime on the diseased holes for disinfection, or drench the diseased holes with 50% thiophanate-methyl 800-fold solution or 50% carbendazim 500-fold solution.

2. Fusarium wilt

[Damage] It occurs from mid-June to early July. At first the leaves and leaf tips of diseased plants droop, showing green wilt, and finally the roots rot and the whole plant dies.

[Control] In the early stage of disease, pull out diseased plants and drench the diseased holes and the roots of nearby plants with 50% carbendazim 500-fold solution, or 50% thiophanate-methyl 800-fold solution, or 40% carbendazim suspension concentrate 500-fold solution to prevent spread.

3. Angular leaf spot

[Damage] It harms leaves and occurs in rainy seasons. At first, water-soaked lesions appear, then gradually expand into angular brown lesions. In severe cases, leaves dry up and fall off, causing reduced yield.

[Control] In the early stage of disease, spray with 1:1.5:120 Bordeaux mixture, or 72% agricultural streptomycin 1000-fold solution, or 77% Kocide 500-fold solution. Spray once every 7-10 days, for 2-3 consecutive sprays.

4. Brown spot

[Damage] It harms leaves. From May to June, nearly round lesions form on the leaf surface, light brown in the middle and dark brown at the edges, with light black mold-like growth. It is severe in humid rainy seasons.

[Control] Remove diseased leaves and burn them. Spray with 1:1:120 Bordeaux mixture, or 64% oxadixyl wettable powder 500-fold solution, or 58% metalaxyl-mancozeb 500-fold solution.

5. Septoria leaf spot

[Damage] Lesions on both sides of leaves are polygonal, initially 1-3 mm in diameter, dark brown, and leaf color turns yellow. In severe cases, lesions merge and leaves die.

[Control] In the early stage of disease, spray with 50% Ridomil 1000-fold solution once every 7 days, for 2-3 consecutive sprays.

6. Aphids

[Damage] Adults and nymphs gather on tender shoots and tender leaves to cause damage, making plants grow poorly and unable to normally produce new buds and new leaves.

[Control] Spray with 10% imidacloprid wettable powder 1000-fold solution, or 50% pirimicarb wettable powder 2000-fold solution, or 40% dimethoate emulsifiable concentrate 1500-fold solution. Stop applying half a month before harvest to avoid leaving toxic residues.

7. Red spider mites

[Damage] It occurs severely in high-temperature and low-humidity seasons from June to August. Affected parts first show small yellow-white spots, gradually becoming large yellow-brown scorched spots, and finally the whole leaf turns yellow and falls off.

[Control] Spray with ChongmanLike 1500-fold solution, or 40% Sukelang, or 1.8% abamectin 3000-fold solution.

8. Silver-striped leaf moth

[Damage] The larvae of the silver-striped leaf moth bite leaves into holes or notches. The larvae hide on the underside of leaves during the day and mostly feed on the leaf surface at night and on overcast days.

[Control] Spray with 90% crystal trichlorfon 1000-fold solution, or 25% chlordimeform aqueous solution 300-350-fold solution.

9. Leaf roller

[Damage] The larvae of the leaf roller spin silk and roll leaves on young buds and young leaves, hiding inside and chewing the leaves.

[Control] Spray the leaf surface with trichlorfon 300-400-fold solution.
