TL;DR: In this paper, the effects of herbicides on canopy variables could be detected by sensors, two crops were used as models and treated with herbicides at BBCH 20 using a logarithmic sprayer.
Johnsongrass (Sorghum halepense) Seed Dispersal in Corn Crops under Mediterranean Conditions
TL;DR: It is concluded that the major role of sexual reproduction in johnsongrass population dynamics may be to spread the risks, promoting dispersal in time and space.
Reliability of a Visual Recognition System for Detection of Johnsongrass (Sorghum halepense) in Corn
TL;DR: In this article, the authors evaluated the reliability and profitability of using maps of Johnsongrass patches constructed at harvest to predict spatial distribution of weeds during the next cropping season.
