Spring dwarf
Feeding at leaf tips in rice results in whitening of the top 3-5 cm of the leaf, leading to necrosis (described as “White Tip” of rice by Yokoo, 1948). There is also distortion of the flag leaf that encloses the panicle. Diseased plants are stunted, lack vigor and produce small panicles. Affected panicles show high sterility, distorted glumes and small and distorted kernels .
