What is DAJOA?

Physical and chemical property of these elements are completely different from those of others due to the difference in atomic structure. DAJOA is a product made of lanthanides that are biologically effective to regulate cell metabolism to promote the performance of plants .

Stimulates plant growth
Makes plant strong
Incrreases productivity
Produce quality products

Directions for the Use of DAJOA

DAJOA can be used for all kinds of crops, such as vegetables, flowers, or fruit trees. Before using as a foliar spray, read all directions. Completely dissolve DAJOA in water, and make sure there are no alien substances in the mixture. After the DAJOA is completely dissolved, spay the leaves until completely saturated so the leaves can absorb the nutrition.

Seedling stage (after seeding to transplanting for crops, sprouting stage for fruit trees): Dissolve 15 grams of DAJOA into 20 kilograms of water.
Tillering stage: Dissolve 20 grams of DAJOA into 20 kilograms of water.
Florescence stage to 30 days before harvest: Dissolve 25~30 grams of DAJOA into 20 kilograms of water.
Please spray DAJOA every 20 days for continuous harvesting crops (hot pepper, vegetable, etc.), and for other non-continuous harvesting crops, spray three times or more during the whole growing period.

Precautions

Crop may stop growing for several days because of heavy concentration of DAJOA.
Please reduce the concentration of DAJOA when used in green houses during the summer.
Please avoid mixing DAJOA with alkaline chemicals or alkaline fertilizers.
Please store DAJOA in cool and shaded areas.
