Prevention and Control of Downy Mildew on Winter Wheat Shelter

Both the seedlings and the adult plants can be affected. The adult plants are affected more seriously. The main damage is the leaves. The diseased leaves spread upward from the lower part of the plant. The early leaves have yellowish-yellow round or polygonal lesions. When the humidity is high, the leaf spot length is longer. White mold layer.

Control methods:

(1) Agricultural control: Increase organic fertilizer, close planting, timely cultivating, and prohibit flood irrigation.

(2) Chemical control at the early stage of disease: 50% chlorothalonil dust sprayed at a dosage of 1 kg/mu; 40% diethylphosphorus aluminum wettable powder 200 to 250 times or 72.2% water 800 times liquid or 72 grams of 600 times 600 times liquid spray, 7 to 10 days once, and even spray 2 or 3 times.

1000Hz High Frequency LiDAR System

JRT High Frequency Range LiDAR Sensor is 2021 new product, that's a low-cost tof sensor but High frequency (up to 1000Hz). With 5cm high accuracy, the LiDAR Module can measure 80m.
