Wales coach Gareth Jenkins is worried by the grassroots gameWales coach Gareth Jenkins says he is alarmed by the rise in violent incidents in grassroots rugby.
The Welsh Rugby Union has promised to crack down on ill-discipline among youth players, parents and coaches.
In the 2005/6 season the WRU under-19 disciplinary committee dealt with 139 sendings off and 100 cases of abuse of referees or breaches of conduct.
"A respect for the laws of the game and for all players, referees and officials is part of our job," Jenkins said.
Particularly worrying for the WRU is the poor example being set by some coaches to their young charges.
One coach had to be dragged off the pitch after abusing an opposition player in an under-11 match.
Jenkins added: "It is worrying to learn that coaches are responsible for a large percentage of recent breaches of the Union's code of conduct.
"A coach's role, particularly where young people are concerned is to nurture talent, to bring out the best in all players and to be a role model at all times."
