Seed coating
Seed coating is an effective means to prevent seed propagation, soil-borne diseases, and underground pests, and it can also reduce post-control drug use. Combining with the occurrence characteristics of pests and diseases in the region, targeted selection of the types and contents of the coating agents ensures the control effect.
Weed control
According to soil moisture science to select weed control methods, such as summer corn after sowing more rainfall, soil moisture is good, it is recommended to close the weeding; if less rainfall, poor soil moisture, weeding recommended stems and leaves. Closed treatment can use 40% acetic anhydride suspension agent 300 ml or 40% isopropyl straw suspension agent 200 ml per mu; stem leaf treatment can use 4% Nicosulfuron oil suspension agent 40 ml +38% Atrazine Suspension 70 ml.
Seedling Pest Control
When the armyworm reaches the prevention and control index, it can be combined with the prevention of weeding before the seedlings are sown and the “two kills†will be carried out. The lepidopteran pests such as armyworm can be controlled with 4.5% beta-cypermethrin EC and 48% chlorpyrifos EC. For seedling stage PUMA, 10% imidacloprid WP, ​​1.8% avermectin EC or 25% Thiamethoxam in water can be used Agent control.
Mid-late pest control
The control of corn borer can release eggs of Trichogramma at the beginning of adult oviposition, with the release amount of 10,000 heads per mu, which is generally released once. The severe block of individual corn borer can be released twice. The spraying of Bacillus thuringiensis (Bt) preparations at the end of the heart leaves, or the rational use of pesticides such as chlorantraniliprole, thiamethoxam, etc., and acetosin salt, to improve the control effect, and to treat other pests. The control of leaf spot diseases can be sprayed with difenoconazole, diniconazole, pyraclostrobin, and Jinggangmycin A during the big bell-mouth period of corn, and sprayed once every 7-10 days depending on the incidence. .
Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.
