Abstract

PURPOSE: To germinating and rooting preventive that is composed of powder particles coated with a water-repellent film made of asphalten, thus repelling water, including no water inside and making it impossible for seeds to germinate and root, further it can be easily produced, transported and supplied in large quantities inexpensively.
CONSTITUTION: Powder particles are treated with extremely thin and water-repellent film of ashalten on the surfaces and the particles only or its mixture with soil or sand is used as the preventive. As the powder particles, are used fly ash, volcanic ash, fine particles of calcium carbonate, naturally occurring sand of mineral sand or their mixture. Asphalten is dissolved in a solvent such as light oil or kerosine boiling at 180W400°C and the particles heated up to 120W200°C are added to the asphalten solution under stirring to form the coating films on the surface. The weight ratio of the asphalten to the particles is less than 2%.
