Pentosan is a pesticide fungicide commonly used in China to control rice crop diseases, also known as Hesuining, carbendazim, and pentacyclone; it has long protective effect and long duration of drug effect, and it is resistant to Rhizoctonia solani. The disease caused has a specific activity, is low in toxicity to mammals, is harmless to the environment, and is highly safe to the user.
I. Overview of pentosan
Pentosan is particularly effective against economically important crop diseases caused by Rhizoctonia solani. The agent adheres easily to the surface of plant tissues and is easily absorbed by the hyphae of Rhizoctonia solani. It has a strong inhibitory effect on the growth of mycelium, resulting in a morphological disorder in the development of mycelium. It can be used to control various crop mites and seed-borne diseases caused by Rhizoctonia solani, such as Sasaki sylvestris, sugar beet leaf rot and root rot on rice, Rhizoctonia solani, rice sheath blight , stalk stalk rot, potato black smut, etc., because the drug is not effective against other soil parasites such as Pythium and Fusarium, it is recommended to mix with other fungicides such as Kezhen powder, Pedan and other pesticides .
Second, the use of pentosan
Urea fungicide, no systemic, has a special effect on the disease caused by Rhizoctonia solani. Used in rice, potatoes, vegetables, ornamental plants, etc. For the prevention and control of rice sheath blight, a 25% wettable powder foliar spray is used, and the dosage per hectare is 0.15-0.25 kg. For the control of potato black shank, seed dressing with 1.5% non-bleaching powder 0.5kg/100kg tuber. It is used to control the growth of Saskatchewan, and sprayed twice with 150-250 g of active ingredient per hectare.

4. It can be mixed with pesticides such as Kezhen Powder and Paidan.

Centrifuge tubes are used in laboratory centrifuges, machines that spin samples in order to separate solids out of liquid chemical solutions. The centrifuge tubes can be made of glass or plastic, and resemble miniature test tubes with tapered tips. They are mainly used in series test like the centrifuge of nucleic acid
