Corteva Agriscience Salibro product manager, Dan Cornally, said nematode control options in the past have typically been quite disruptive to beneficial fauna contained in the soil.
“Nematode control can be very challenging, and many of the current options available to growers are not IPM friendly which results in significant disruption to soil beneficial organisms, they are also generally considered higher risk to growers and the environment.
“Salibro is quite different, it is much lower risk to applicators and the environment. It is also a very effective nematicide that controls root-knot nematode and has negligible impact on the beneficial species that help suppress pests and diseases for healthier soil.”
Mr Cornally said Salibro has a unique mode of action and can be used at relatively low rates.
“Salibro affects the co-ordination of the nematode, meaning they are unable to move, feed and infect plant roots within hours of treatment. Death will occur in a couple of days as nematodes cannot move or feed effectively.”
In treated soils, parasitic nematodes hatch and juveniles are exposed to Salibro as they move in films of water within the soil in search of a host root. This exposure will result in control of these newly emerged juveniles.
Soil temperature does not have any impact on the performance of Salibro and effective control is observed both at low and high soil temperatures, i.e. 4 to > 35 °C.
“Salibro will typically provide root protection from 20 to 50 days so is an excellent option for growers needing effective robust control of root-knot nematodes.”
Mr Cornally said Salibro offers excellent flexibility in terms of application timing and methods.
The approved use patterns are:
“Salibro has been extensively tested across Australia targeting important horticultural areas on a range of soil types since 2013 and there has been no crop injury or significant impact on crop vigour throughout those trials,” Mr Cornally said.
One of the trials sites was in Bundaberg, Queensland, and included a planned trial of the new product in sweet potatoes, carrots and capsicums.
“This was a particularly useful trial as there were very high rates of nematodes in the soil and Salibro was compared to untreated plots and those treated with current industry nematicides,” Mr Cornally said.
“This trial demonstrated the excellent crop safety of Salibro and its ability to control nematodes to produce high yields of quality vegetables.”
In the carrot trial at the site, the untreated section produced very small and deformed vegetables whereas the Salibro plot had large quality carrots.
Mr Cornally said the advantages of Salibro over current nematicides were evident and would be welcomed by growers in the coming season.
“This product has application flexibility and will help growers produce consistent, quality vegetables while looking after their soil.”
Salibro is a nematicide which contains the novel, non-fumigant, active ingredient Reklemel the first sulfonamide nematicide .The mode of action of Reklemel, while mechanistically unknown, has been extensively studied and is different from all other currently available nematicides.View now
