Agricultural Technology Lecture | Attention! Prevent wheat scab in time!

Wheat scab mainly affects the ears of wheat. At the beginning of the occurrence, small water-stained light brown spots appear on the spikelets and spikelets, which gradually expand to the entire spikelet. When the humidity is high, a pink gelatinous mold layer is formed on the lesions. In the later stages of the disease, the spikelets above the affected site form withered white spikes.

Wheat scab is a national first-class crop pest and disease, which is a typical climatic disease. The severity of the occurrence of scab mainly depends on the weather conditions during the wheat heading and flowering period: if there is even rainy weather and the temperature remains above 15 °C during the wheat heading and flowering period, the scab may be epidemic damage. The toxins produced by the pathogen of scab will affect the quality of wheat, and the number of diseased seeds will not be edible if the number of diseased seeds exceeds 4%.

At present, the wheat in our city has entered the heading and flowering period, on April 26, there were thundershowers in our city, according to the forecast of the municipal meteorological department, there were thundershowers on April 29, and other periods were mainly sunny to cloudy.
