Keep immersing seeds in Atonik solution with density 1/1000 (1ml of Atonik to 1 litre of water) for 20-30 minutes to promote germination, then sow seeds into the soil.

Mix coconut fiber (fully cleaned) with husked ash (desalted) and manure at the rate of 35% coconut fiber + 35% husk ash + 30% manure.

Sow the seeds in about 1cm of depth. If the sowing is too deep, seeds will slowly germinate or will not germinate at all.

You should place the seedling tray in a shaded area for good germination. Keep average soil moisture, not too dry or too moist. Spraying Validacin, Rovral, Carbendazim, Ridomil, Kasuran to prevent damping off disease.

Pest and disease management: 

Pests

Insects such as aphids, white fly, green leafhoppers etc. are harmful to leaf stems, young shoot and young fruits, causing the bad growth of plants, reducing the fruit quality and being the vector to transfer virus. Use the pesticide such as Confidor, Trebon, Thianmectin, Radian, etc. to control.

Aphids: Popularly appearing on Papaya. The garden should be ventilated, reject the decayed leaves. Water can be used to clean the fruits when pests appear in a large amount of quantity. Then, we can use the pesticide such as Applaud, Butal, Bassa, Regent, Confidor, Movento 150 etc.

Note, when using the pesticide, spray with adhesives because populations of aphids have thick white wax covered. If there are many kinds of trees in the same garden, should spray over the other trees also. Ensure the killing of young aphids, and other ones hiding on other host plants.

Diseases

It is difficult to prevent the diseases caused by virus. Though Sinta F1 papaya are resistant to certain viruses, proper hygiene is also necessary in combination with using the pesticide to reject the pests.

Anthracnose, Downy mildew: Properly manuring. Spraying Anvil, Daconil, Topsin, Mancozeb.

Damping off, or fungi affected: The soil should be kept dry and well drained. Using the fungicide such as Ridomil Gold, Dithane, Aliette, Vilaxyl, Canthomil, etc. to spray or water around the root of trees.
