By 2000, 11 major stored product pest species had been found to be highly resistant [16]. the application rate for phosphine is 1.5 grams per cubic metre, which in tablet form equates to three tablets per 2m3. In winter, it is cold and dry; in summer (May-August about 100 days), it is hot and humid. Trove is a collaboration between the National Library of Australia and hundreds of Partner organisations around Australia. Spread phosphine tablets evenly across trays before hanging them in the head space or placing them level on the grain surface inside a gas-tight, sealed silo. In this presentation, we will cover … Different types of fumigants . This highlights the importance of monitoring grain regularly and at least 17 days before out-loading to allow sufficient time to fumigate if required. How to measure and calculate dosage rates for grain fumigations . When determining how much phosphine to apply, it is important to treat the entire storage volume, regardless of how much grain is contained inside. In addition, for the fumigation of very large bulks over extended periods higher dosage rates may be required. 2y�.-;!���K�Z� ���^�i�"L��0���-�� @8(��r�;q��7�L��y��&�Q��q�4�j���|�9�� If properly generated according to the method given here, O.45 kg (1 lb) of sodium cyanide will generate 0.25 kg (8 oz approximately) of HCN gas. 9.The current recommended dosage rate for phosphine is 2g of gas/ton or 1.5g of gas/m3 (3g of aluminum phosphide = 1g of phosphine gas). At grain temperatures above 25°C, the standard seven days is required. The common thing between all protocols is that the fumigator needs to measure the concentration continuously as well as the product temperature. For many building fumigations at temperatures above 20°C, the dosage of HCN gas recommended is 8 g/m³ (8oz/l 000 ft³ ). The goal of the fumigator is to maintain 200 parts per million after 96 hours when the grain tem- perature is above 65° F. The label recommends 450 – 900 pellets/thousand bushels for grain bins. All pesticide applications must accord with the currently registered label for that particular pesticide, crop, pest and region. Use of ProFume can reduce fumigation times by two weeks or more in comparison with a phosphine blanket fumigation. When fumigating grain, the phosphine gas dosage rate depends on the type of storage, the pests to be controlled, and commodity temperature.
