phosphine tablet

Categorised under:

Catalogue: Ground Cover
Phosphine needs seal of approval.. Limiting correctly applied phosphine to sealed storages and is the only way to economically control all insects regardless of resistance level or growth stage... The higher the level of resistance, the higher the concentration of phosphine and/or the longer the fumigation period required to control all the life stages of the insect (figure 1)...

"It is critically important that growers implement best practice when storing grain, particularly in relation to fumigation," said Peter Botta, grain storage specialist for southern New South Wales, Victoria, South Australia and Tasmania... To control pests at all life stages and prevent resistance, phosphine gas concentration needs to reach 300 parts per million (ppm) for seven days (when grain is above 25C) or 200ppm for 10 days (between 15-25C)... The withholding period is two days after ventilation the total fumigation process requires seven to 10 days...

The spear is pushed horizontally through a small hole in the membrane into the grain at about chest height... One of Australia's leading grain-storage specialists says silo bags infested with weevils can be successfully and safely fumigated with phosphine using a three-step process... Working with DEEDI's Dr Andrew Ridley and Queensland grain growers Chris and Roland Cook on a Cooperative Research Centre for National Plant Biosecurity (CRC NPB) research project, Mr Burrill found effective fumigation is achieved by: ensuring the silo bag is well sealed; applying the correct dose of phosphine spaced along the bag; and venting the gas safely...
