And for most of the southern Riverina and North-East Victoria that means the canola crops are starting to bloom.

The sea of yellow is starting to take over paddocks across the region and this season the crops have "massive potential".

But the threat of diseases such as blackleg and sclerotinia during this time can be damaging to farmers.

That is where Albury-based Hazair comes in - spraying crops from the skies.

"The crops are looking so good this year, the farmers don't want to touch them," operations manager and pilot Adam I'Anson said.

"You can lose between 5 and 10 per cent yield if you spray using tractors and machines.

"With us you eliminate that loss, plus the plane can whip over it in half the time.

"With the potential with the crop this year after the drought we have been having more and more farmers opting for aerial application to keep as much of their crops growing."

The company, which has been flying over crops since 1960, has had to expand to keep up with demand and has opened another base in Brocklesby.

And for their primary pilot the work continues to combine his two loves - flying and farming.

"I guess for me I have grown up flying and farming so this job really is perfect for me," he said.

"The view isn't too bad either this time of year.

"I guess a lot of people who aren't involved in farming wouldn't know we exist and is a cool sight seeing us spray over the canola fields."

Mr I'Anson said their new base combined with their new Air Tractor 402 plane would help them "better serve their customers".

"We like to stay local and support our local farmers and the new plane definitely helps us do that," he said.

"It is a single-seat aircraft, turbine-powered and has a 1500-litre capacity to hold chemicals.

"We use it for both spraying and spreading and generally all round is the most versatile.

"It has an air conditioner and heater too which makes it very comfortable while you are up there."

But like most farmers, Mr I'Anson said there "has to be more rain".

"We need rain to continue as much as farmers do," he said.

"It keeps all of our businesses going.

"And this year has so much potential - if it keeps raining we will stay busy."
