| Abstract: | This investigation indicated that the spatial distribution pattern of the loose smut of wheat Ustilago tritici (Pers. ) Jens. ] in the wheat fields fits in the negative binomial distribution. Part of these pattern belongs to the A pattern of Neyman distribution. Then we suggested the technology of sequential sampling and theoretical sampling and distribution points of random sampling of the loose smut of wheat by using the Iwao and Kuno and Green and Iwao-Kuno methods which may be useful for reference to forecast and control this disease. |
