Weeds absorb quinclorac faster, generally no rain will affect the control effect of quinclorac after 2 to 3 hours after application, but it will reduce the herbicidal effect within 1 hour after application. Make up the spray. The transmission of quinclorac in the weeds is poor, mainly manifested by contact killing, and only the parts exposed to the drug will be killed directly. Studies have shown that quinclorac is used to control valerian above 3 leaves. If the base of valerian is submerged in water during application, it can only kill part of the surface of valerian, and the base of sedge that is submerged in water is not dead. It can quickly sprout new buds and grow normally and heading. It can be inferred that the quinclorac acid that enters the field with rainwater after application does not have a good killing effect on the sedge which is exposed above the water surface. Considering that excessive application of quinclorac at the 3-leaf stage of rice may cause phytotoxicity to rice, it is recommended to use herbicides such as Inagi, which is safe for rice, when it is recommended. Bensulfuron-methyl can still play a role after it has been drenched into water. It does not need to be replenished when the field water is not discharged after application.
Cylindrical Lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either Plano-Concave Cylinder Lens or plano-convex cylinderical lens configurations. Plano-Concave Cylindrical lens has a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylinder lens has a positive focal length, which makes the cylindrical lens ideal for collecting and focusing light for many imaging applications. Every sizes,materials cylindrical lens are available according to your detailed parameters.
Some styles of cylindrical lens have antireflective coatings to increase the transmission of light through the cylindrical lens.
Fused silica cylindrical lens is ideal for demanding laser machining and medical applications.
