The @GuardianAus refuses to publish information that allows a correct and more balanced view on pesticides. It’s the third separate occasion that they have done so. Disappointing double standards for a publication that believes in information equality. So here it is. #agchatoz

Budworm moths are being captured in pulse crops in the Geraldton region and eastern grainbelt towards Southern Cross. This is a sign to consider sweeping your crop and using the CropScout app to determine if 🐛numbers are above threshold.
The recent #PestfactsWA newsletter by @DPIRDbroadacre advises that #nativebudworm moth numbers are beginning to increase in some areas in WA. This map is of trap captures from 1 June – 26 Aug from @cesaraustralia's MothTrapVisWA page. Read more: https://t.co/5RF6Sz4rCQ

Weekly budworm moth flights from our trapping network - June to now. Get those sweepnets out and consider traditional thresholds to be on the low end with the current grain prices. More info in this weeks #PestFax, @iMapPESTS @DPIRDbroadacre @GRDCWest
