Laboratory of Plant Production Science  (Weed Science dep.)

Hidehiro Inagaki

Weed control is an important issue in agriculture and green area management. Weed science is the study of weeds to clarify the characteristics of weeds and to develop methods to control weeds.

Although it seems that weeds grow anywhere, they have special characteristics in order to adapt to specific environments such as fields and roadsides. The major theme of our laboratory is “What kind of plants are weeds? - From weed control to weed management.” For this theme, we aim to clarify the ecology of weeds, develop weed control methods, and develop weed utilization.

Although the main themes of our laboratory are as described below, undergraduate students may set their research topics freely based on the interests of individual students.

1. Clarification of the physiological ecology of weeds
In order to control weeds, it is necessary to understand the ecology of weeds. In particular, weeds are plants with a large adaptive capacity to changes in the environment. Therefore, we study the basic physiological ecology of weeds, intraspecific mutations, and environmental responses of weeds.

2. Development of integrated weed management.
In order to effectively control weeds, we study the development of integrated weed management technology to suppress the occurrence and growth of weeds.

3. Improvement of functional biodiversity by vegetation management
While weeds are a source of pests, they may also become source of natural enemies. Therefore, it is possible to reduce pest insects and increase natural enemies through vegetation management. We aim to develop an effective management method to increase functional biodiversity. We also study biodiversity of rural ecosystems including weeds.
