How to prevent and control the rhizome in the ear

At the earing stage, borers mainly include corn borer, sorghum stripe and cotton bollworm, etc., mainly corn borer. The primordial larvae initially feed on the filaments of the corn, then feed on the tender grains, drill the pods, cause grain defects and cause mildew. After 4 years of age, the head or stalk of the corn ear was drilled, which impeded the development of the ear and reduced the yield. The pod bore was easily broken and the quality and yield were reduced. Due to the high corn plant density and the high field density, it is difficult to control the rhizomatous phase in the panicle stage by spraying. It is possible to use chlorpyrifos granules at the big bell mouth stage to control the corn ear of corn at the ear stage, or to lay eggs at the ear stage. Initially, Trichogramma released control. The subsequent spraying with phoxim, cypermethrin, chlorpyrifos and other insecticides from 1500 to 2000 times to spray the ear of the fruit and the leaves of the upper and lower leaves, has a good control effect, or on the top of the corn ear or on the filaments 50% zinc sulphate EC and other agents 300 times 1 to 2 drops, the control effect of the panicle ear pests is good.

Micro Laser Distance Sensor

New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.). The electronic distance sensor is a very small Laser Distance Sensor, but high resolution up to 1mm and long distance measuring sensor - teachable measuring range of up to 30m. Extremely accurate distance sensing sensors, errors down to ± 1mm. And the mini sensors and measurements support continuous measurement function, great for compact solutions(eg: robots) with the smallest Laser Distance Sensor of the world!
