Rice seedling disease is mainly caused by seed-borne bacteria, and drug soaking is an effective measure to control the occurrence of the disease. It was learned from Jiangsu Pesticide Research Institute Co., Ltd. that it had good control effect on rice seedling disease by soaking seeds with 25% cymene suspension of 3000% solution created by the company. Flap Wheels with shaft are made of multiple abrasive sheets attached to a core for fabricating, deburring, cleaning, polishing, and finishing jobs in metalworking applications. The sheets wear away during jobs, constantly exposing fresh abrasive coating to provide an even finish. Each grit flap comes in contact with the work piece at a slightly different angle, which prevents scratches. Because abrasive flap wheels conform to the shape of the surface material, they are commonly used to finish complex shapes and tight contours on a work piece. Flap wheels attach to grinders, drills, impact wrenches,or handheld rotary tools. They are either pre-mounted on a central hub, or unmounted for attaching to a compatible arbor.
Suitable for grinding the inner hole and camber of all kinds of metal and non-metal materials, select the suitable size of flap wheel with shaft for grinding. Remove burrs, rust, metal (plastic) and other surface grinding, internal and outter surface grinding, the grinding before painting, etc.Polishing, deburring, and removal of pits, burrs, and scratches. Remove parting lines and provide a uniform scratch pattern on all metals. The 1/4 inch stem allows for easy mounting on a die grinder or right angle die grinder.

According to reports, cymene has protective and therapeutic effects, has systemic and transmissive properties, and has high antibacterial activity against mycelial growth of rice seedling pathogens. By using this drug to soak seeds, it can control rice seedling disease hazards throughout the process. . Cyanolide has a novel mechanism of action and does not interact with bactericides of five different mechanisms of action: benzoimidazoles, ergosterol biosynthesis inhibitors, methoxy acrylates, dithiocarbamates and substituted aromatics. Resistance, that is, there is no cross-resistance with common fungicides such as thiabendazole, carbendazim, thiram, chlorothalonil, thiophanate-methyl, prochloraz, tebuconazole, azoxystrobin.
A large number of experimental demonstrations showed that the 25% cymene suspension was soaked with 3000% liquid, the ratio of rice to liquid was 1:1.2, the temperature was controlled at 15-20 °C, and the immersion was generally 2 days. sowing. Soaking seeds with this drug has no adverse effects on the growth and development of rice throughout the growth period, safe and no phytotoxicity, and has good control effect on rice seedling disease. The control effect at seedling stage is 100%, and the control effect at the end of tillering is 96.99%~ 100%, the control effect at the heading stage is 76.05% to 98.86%.
