Abstract

Weeding strategy consists of following two issues.
The first relates to cropweed competition.
The other relates to reduce the seed amount of annual reproductions.
In this report, a simple weed reproduction model was developed to predict the effect of field operations on the reproduction number.
The amounts of annual weed reproduction were consisted of emerging function, elongation function and maturing pattern.
It is described as a function of operation schedules.
