Grape sprouts for preventing pests and diseases
The spring is the season when the grape sprouts grow leaves, shoot elongation, heading, and flowering. It can start disease prevention when the grape is germinated from 3 to 5 leaves, spraying once every 7 to 10 days, especially after the rain. Drug protection, and pay attention to cultivator weeding. This period is mainly to prevent grape black spot disease, gray mold, rust and so on. For example, black pox can be used 8000 times Dupont Fuxing, gray mold can be controlled by 1500 times faster Crohn. In addition, 800 times more carbendazim, 800 times mancozebite, 800 times more than the Sensen zinc control. 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.
