Recently, in many places, rice seedlings in many places showed abnormalities such as dark seeds and flower seeds, and some farmers thought that they were grain borers or other diseases. So what is the reason?
Answer: 1. During the development of spike, part of the spikelets will stop developing due to high temperature, etc., a heading will be able to see that some of the glume husks are white and brown.
2. Some degenerate spikelets are still green when the panicles are drawn out, but their disease resistance is weak and they are easily invaded by some weak parasites, causing the glume to turn brown.
3. The glume of normal spikelets after heading is mechanically damaged by wind and rain, and is infested by weak parasites. Symptoms such as browning and mildew appear in the husks. These granules are normally grouted early in the florescence, and the rain during the spike period is frequent. The years often result in damaged or even mildy grains due to husk rot, causing rice yield and quality to decline.
4. Combination of panicle blasting stage and other diseases, spraying pyraclostrobin (BASF rice only obtains rice registration), bacteriochlor and other bactericidal broad spectrum drugs, if necessary, add methylthiobacillus Ling, carbendazim, etc., can reduce the infection of saprophytic bacteria, and can also prevent and treat possible bacterial blight disease and other diseases.
