Rice brown spot dataset

Rice flax spot. Rice flax leaf spot occurs in all rice regions of China, which mainly endangers rice. From seedling stage to harvest stage, the disease can occur, and the above-ground parts of rice plants can be damaged, mostly leaves. Leaf damage was initially small brown spot, then expanded to oval brown spot. Because of the size of flaxseed, it was called flaxseed spot. The edge of the lesion is obvious, and there are often yellow halos around it. The center of the lesion is gray-yellow or gray-white in the later stage. In severe cases, the lesions are dense and often combined to form large irregular spots. The lesions on grains are similar to those on leaves, and can be extended to whole grains. When the humidity is high, a large number of black villous mildew layers are produced on the glume joints and the surface of grains. The symptoms of panicle neck and branch injury were similar to rice blast, but the diseased part was dark brown and the discolored part was longer. The disease is easily confused with rice blast, and there is no necrotic line at both ends of the lesion, which is an important difference from rice blast. [Control methods] {Control methods}. [Seed treatment] Soak seeds in 1000 times liquid of 40% Kewensan Emulsion or 50% Carbendazim Wettable Powder for 2 days. [Agricultural control] The straw in the diseased field can not be returned directly to the field. Strengthen fertilizer management, achieve sufficient base fertilizer, early topdressing, organic fertilizer and phosphorus, potassium fertilizer combined application, especially in potassium-deficient fields to increase the application of potassium fertilizer. Early shallow water irrigation, timely and moderate roasting field, later dry-wet alternation, so that rice seedlings mature to old. [Pharmaceutical control] At seedling stage, rice blast Ling (Chunlaimycin) was used to control the disease. After transplanting, the rice sprout was sprayed together with the combination of trichoderin and Tricyclazole.

稻胡麻斑病（Rice flax leaf spot）在中国各水稻主产区均有发生，主要为害水稻。该病自苗期至收获期均可发病，水稻地上部各器官均可受害，其中以叶片受害最为常见。叶片染病初期表现为褐色小点，后逐渐扩展为椭圆形褐色病斑，因病斑大小与胡麻籽相近，故得名胡麻斑病。病斑边缘清晰，周围常伴有黄色晕圈；发病后期病斑中央呈灰黄色至灰白色。病情严重时，病斑密集且相互融合，形成不规则大型病斑。谷粒上的病斑与叶片上的症状相似，可蔓延至整个谷粒。当湿度较高时，颖壳接缝处及谷粒表面会产生大量黑色绒毛状霉层。穗颈和枝梗染病的症状与稻瘟病相似，但病部呈暗褐色，变色区域更长。该病极易与稻瘟病混淆，但其病斑两端无坏死线，这是与稻瘟病的重要鉴别特征。【防治方法】【种子处理】使用40%克瘟散乳油（40% Kewensan Emulsion）或50%多菌灵可湿性粉剂（50% Carbendazim Wettable Powder）的1000倍液浸种2天。【农业防治】病田秸秆严禁直接还田。加强肥水管理，施足基肥，早施追肥，有机肥与磷、钾肥配合施用，尤其在缺钾田块需增施钾肥。灌溉采用前期浅水勤灌，适时适度搁田，后期干湿交替，促使水稻成熟落黄。【药剂防治】苗期可喷施稻瘟灵（春雷霉素，Chunlaimycin）防治病害；移栽后可结合施用木霉菌剂（trichoderin）与三环唑（Tricyclazole）进行喷雾防治。
