Sure. It's a project initiated by a group of local farmers and researchers (meteorologists and an enviro engineer) in the state of South Australia, and funded by state government grants, to install high-precision weather stations throughout all the agricultural regions of that state.
Data is updated every 10 minutes, and it reports specific readings/calculations indicating whether it is safe to spray pesticides [1]. More recently (since I left the project) they've added in predictive calculations derived from ML models, that can indicate whether it's likely to become risky or stop being risky for spraying in the next two hours.
It also reports conventional meteorological measurements (temperature, humidity, rainfall, wind etc) and relevant calculated values relating to fire risk, seasonal thermal accumulations (growing degree days), evapotranspiration etc - so it is a general-purpose weather/environmental data service for growers.
It seems to be very powerful and useful, however it still relies on growers remembering to look at the app and make the right decision each time they're thinking of spraying, and a combination of education, social pressure and law enforcement is needed to encourage responsible conduct.
The biggest issue they're trying to mitigate is damage to other crops [2] but pesticide residue in food/beverage products is another significant factor, as it can affect other producers' organic/biodynamic certification status, and some countries require imported food/bev products to pass very stringent maximum levels of pesticide residue.
You can search for "south australia mesonet" for more details.
[1] The most significant factor for this is the presence of thermal inversions, and this requires temperatures to be measured at ground level and 10m up, hence the need for quite elaborate/costly public infrastructure rather than relying on growers having their own weather stations.
[2] I started typing "nearby crops", but one of the major issues is that the combination of thermal inversions and winds can mean that residues can be carried long distances - 40km+ before being deposited onto other crops when the inversion reverses, which means it's hard/impossible to identify where the residue came from, meaning ex-post liability attribution for statutory or civil penalties can be impossible.
