Answer: At this stage, leafhoppers, aphids, leaf roller moths and other pests are mixed in the field and damage is aggravated. Control methods: Combine the summer cuts to improve the ventilation and light conditions of the orchard, cut off the shoots and shoots, remove insects and insects, and bring them out of the park for destruction. According to the occurrence of pests and orchards in the orchard, the corresponding fungicides, insecticides and acaricides were selected and sprayed in the whole garden according to their respective recommended amounts. Insecticides can use 4.5% beta cypermethrin 1500 times or 25% diflubenzuron suspension 3000 times. Acaricides were selected from 15% of Lingling EC 1500 to 2000 times or 20% of quinophthalate ether 4000 to 5000 times.
Short range distance sensors from JRT combine highly precise measurement results with quick and reliable response. Short distance sensor module use single-transmit and single-receive measurement technology and can be used to measure a distance or monitor the slow moving objects. For the laser pointer distance measure, also called optical range sensor, can measure legth, width, depth. Laser rangefinder transducer with rxtx has been widely used to industries.
