Grain storage entomologists are closely monitoring resistance of insects to the fumigant phosphine and are advising growers and grain handlers to review their control practices... The frequency of resistance of grain insects to phosphine fumigant has steadily increased in all species since the mid-1990s... Scientists lead a national resistance monitoring program which provides information on the presence of and trends in resistance to phosphine and assists grain handlers by providing information on managing resistance and control options...

x Make use of available testing services to determine nematode species and levels, but be aware that PreDicta-B cannot currently detect some of the nematodes present in WA crops... Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 72.. Overall, lupin was resistant, but Mandelup and Belara resulted in a nematode multiplication rate > 1...

The expected outcomes of this project were detailed in the project specification document: "Early warning of the emergence of new resistance and spread of known resistance... Once resistance was detected and we had confirmed that its potential impact on the grain industry would be significant we initiated an extensive program to establish fumigation protocols to combat it... Our survey has shown that resistance is common in L. bostrychophila and occurs in the other two species (Table 6)...

For more than 40 years Phosphine has been a safe and reliable means of controlling grain storage insects... 210.62: Chris Newman: 213.189: at the situation on this particular farm, Michelle had 216.86: already indicated that it was starting to look very interesting and so I first went 222.829: up to the farm and assessed the situation, discovered what the 228.11: fumigation practice was; looked at the silos; looked 230.75: at the hygiene around the farm and decided that it was possible that we could do an eradication 237.15: of the insects on the farm... And so I put an environmental trap under the 282.43: silos which was essentially a large rubbish bin full of 285.19: grain and sieved the insects out of that on a regular basis and submitted them to the 290.47: labs for Michelle to test and found that there was 294.05: no strong resistance left in the insects that were flying 297.62: into the farm...

Safety is a three-step process - identify hazards, assess risk and address the hazard... Most lids still require a climb to the top of the silo to inspect rubber seals and latch the lid before the silo will meet a half-life pressure test, required for effective fumigation... Safe and sound on the ground: Ground-operated lids reduce the number of times a silo has to be climbed, but most situations require a climb to secure the lid for effective fumigation...
