Introduction
excessive fertilization or spraying DangDoRyuk a few times does not leat to the drastic increase of saccharinity, but it can be certainly improved if controlling the excessive application of nitrogen fertilization to make an effort to raise saccharinity and using DangDoRyuk drenching and foliar fertilization.
DangDoRuk is organic phosphoric acid compounds as well as highly pure minerals combining natural materials(starch, mineral ore, ceramic, and plant seeds) fermented for more than six months.
Cautions in using DangDoRuk
-When spraying it on leaves, leaves, stem, and fruits all should be fully drenched with DangDoRuK.
-When spraying it through the sprinklers, it is better to make DangDoRuK to soak from the upper soil parts to the under soil parts.
If using DangDoRuK after heavy rain(high humidity) and the excessive application of nitrogen fertilizers, the improvement of saccharinity and sugar synthesis do not work properly. In this case, the intensive use of DangDoRuK alone on leaves(3-4 times every 3-4 days)will increase the sugar content in fruits. As an ecofriendly product containing natural ingredients, DangDoRuK should be used alone in principle and its use in conjunction with agricultural chemicals of strong alkali or same nature should be avoided. In case of applying with more than two agricultural chemicals, test on the harmful effects of the chemicals with small amount is required to be preceded. It may have some deposit on the bottom since it consists of natural ingredients, thus please shake it before use.

Fruits
Apple & pear : From late July, spray on leaves 1-2 times(every 10 days)
- Early-season cultivars: Intensively spray more than 3 times every 10 days
- Mid and late-season cultivars: Spray 1-2 times from July to August and again every 10 days since early
September. Drench and spray on leaves until 10 days before shipment.
Peach
- Early-season cultivars: Spray 2-5 times every 10 days from early June until 3-4 days before shipment.
- Mid and late-season cultivars: Spray after mid June but intensively spray from 2 months before shipment.
Blackberry, blueberry, grapes : Drench or spray on leaves every 10 days from the early stage of coloration.
Sweet persimmon : Drench or spray on leaves every 2 weeks from shortly before coloration.
Tangerine, Hanrabong : Apply fertilizer every 10 days shortly before coloration.
- Greenhouse culture: drenching, foliar spray, and combined fertilization using the sprinklers.
- Field culture: Intensively spray on leaf every 10 days - 3 times until 5 days before the maturity stage
Others : Spray 3-4 times from the early maturity stage
Fruits & Vegetables
-Foliar spray in the early stage of coloration & fattening period should be done every week. When conducted together with drenching fertilization, it is required to be done every 5-7 days, but two times of foliar fertilization after on drenching is ideal.
