Richardson's grounds for concern
The International Cricket Council's Dave Richardson revealed the war against corruption has now extended to educating groundsmen as well as players and officials.

Six umpires were last week provisionally suspended and ICC chief executive Richardson admitted: "It is a war we are fighting.
"Our anti-corruption unit have their work cut out to make sure players are kept away from temptation.
"It's everybody now, unfortunately. Everybody is susceptable - curators, groundsmen - our corruption unit is very aware of what it needs to do."
Richardson was speaking at the launch of the final ICC Champions Trophy, which will be held in England next summer before the Ashes series.
The Champions Trophy, which pitches the top eight one-day nations together, is being scrapped to make way in the international calendar for a new World Test Championship from 2017.
"This is tournament is part of the current rights cycle, as we call it," Richardson said.
"Somewhere in the middle the strategy was changed as far as ICC events are concerned. We have three vibrant formats of the game and it makes sense to hold one major event for each format.
"The World Cup is the pinnacle 50-over event so the Champions Trophy is the one to go.
"In 2017 there will be a World Test Championship which will be the first time we have had a Test event on a global scale."
The Champions Trophy will be played over 18 days with the matches scheduled for Cardiff, The Oval and Edgbaston, which will host the final on June 23.
For England captain Alastair Cook, the tournament offers him a first chance to play in an ICC global event.
And it falls in the middle of a busy two years for the new Test captain, including this winter's tour of India and back-to-back Ashes campaigns at home and away.
"This is a very important event for us as a side. We don't often get the opportunity to play at home in a tournament. We have only won one ICC tournament and we would love to win another.
"Clearly the conditions suit us as a side and we have the opportunity to do something special.
"We have a great winter in India and New Zealand, the ICC Champions Trophy and then Australia.
"It is really exciting as a player. We have a lot of big games coming up and if we play well we can do something special.
"We have an amazing opportunity over the next couple of years if we play good cricket. All that cricket in such a short space of time, we can do something special if we play well."
Under Cook's captaincy, England have risen to the top of the one-day international rankings - but he insists there is more to come from his side.
"We dont feel like we are the number one. We have a huge amount fo potential and work to do," he said.
"Our consistency has to improve to mnaintain our challenge in every game. What's important for me is we keep trying to improve and don't feel like we have achieved anything yet."
