Mainspray Frequently Asked Questions

Some Q & A about us.


Q: What does Mainspray do?
A: Mainspray is a vegetation control business. We spray, mow and slash all weeds (mostly imported ones) for a diverse range of customers and situations. We also plant (West) Australian flora for revegetation programmes in situations such as mine-site and roadside rehabilitation works. In October / November, Mainspray carries out a lot of fire-break spraying for private clients and in plantation situations. In summer our work includes a lot of mowing of dried grasses to reduce fire risks along roadsides, within nature reserves and parks as well private properties.

Q: How dangerous is Glyphosate?
A: Much has been reported recently about the carcinogenic effects of Glyphosate. Some countries have banned Glyphosate following a WHO report. Australian toxicologist, Dr Ian Musgrave, disputes these bans, claiming that it has been proven scientifically proven that Glyphosate is ranked a class 2A carcinogenic, lower than alcohol which ranks as a class 1. He states "In fact, if you tried to get the concentration we see in animal studies, you would have to eat something like half a kilo of Glyphosate a day" - Our pest technicians take every care and follow strict standards when applying herbicides.

All Mainspray's Pest Management Technicians have current First Aid certificates, White Cards, ATV, chainsaw and tractor training,
Basic Work site Traffic Management certificates and full Pesticide Licences.

Q: I've seen people spraying in the rain. Is this ok?
A: Generally you do not spray in the rain or spray when rain is imminent. However there are herbicides that require damp soil prior to spraying and need follow up rain after spraying. These herbicides are absorbed through the root system of the weeds. Some of the herbicides Mainspray uses for specific jobs are perfectly effective regardless of rain or sunshine. In addition to herbicides Mainspray also applies liquid fertilisers, soil conditioners and soil wetting agents, all of which can be done in the rain or while being watered by a reticulation system. Other herbicides need to be applied a set number of hours before it rains and also before temperatures rise above a certain amount in order to work effectively. To ensure we do not over or under spray because of adverse weather conditions (heat, cold, wind or rain), we constantly check weather reports and tailor our jobs accordingly. Our employees know when to stop spraying if adverse weather sets in and if they are using herbicides that require good weather conditions. In fact much of our work depends directly on weather conditions which we must take into consideration when programming our daily and weekly jobs.

Q: I'm not at home during the day but need to have fire-breaks done on our property. What should I do?
A: Many of our clients are unable to be at home when we are spraying their property. Our clients are happy to allow our employees on to their properties as we ensure we know exactly what needs to be sprayed, mowed, planted and even avoided, through in-depth discussions with the client and the use of satellite mapping. If you are on a larger property with locked gates, we can arrange to pick the key up, or have it left in a secret location as happens with many of our clients already. Mainspray has never has a complaint about our staff and access onto private properties.

Q: I have an organic farm next door. Can I still get spraying done without upsetting my neighbour?
A: If a situation arises where we are working near an organic farm or vineyard, Mainspray always talks to the organic farm owner to keep them informed which herbicides we will be using, when we will be spraying and what measures we will take to ensure that spray drift does not happen - for example mowing or slashing near adjoining fence lines, or waiting until there is a suitable wind blowing away from the organic property. Additionally, whenever we can, we programme our spraying when the organic crops have just been harvested or the grape vines are in their dormant period. Usually we find all parties very open and co-operative, once they know Mainspray will do everything possible to ensure contamination does not occur.

Q: Is it safe to spray herbicides?
A: Mainspray company guidelines adhere strictly to all legal and OHS requirements. All Mainspray employees are trained and qualified in the use and handling of any chemical substances and wear the appropriate safety equipment When used according to label instructions most herbicides are safe and effective.

Q: What about the environmental damage? Is it safe to spray herbicides?.
A: Modern herbicides are safe to use if the instructions on the label are followed. Before any new herbicides are given the 'green light' by international regulators, they have undergone rigorous testing to ensure their efficacy in killing weeds and their safety regarding environmental concerns. Mainspray staff use herbicides carefully in all environments and always follow instructions concerning correct application rates.

Q:What is Mainspray's Environment policy?
A:Mainspray personnel have an excellent environmental mindset. We have a comprehensive set of written guidelines which everyone knows and follows. Most of our personnel appreciate the outdoors, love the country with its unique plants and animals and have an interest in gardens and gardening. For them, preventing introduced weeds, such as cotton bush, arum lilies, veldt grass, blackberry, and bridal creeper, destroying our remaining forests, reserves, waterways and working farms is part of the solution to rehabilitating our bush and farmlands.

Q:What if I am allergic to herbicides and cannot be near them for medical reasons?
A:Most shire offices will have a register for organic farms and contact details for people with low tolerance to pesticides. Mainspray endeavours to keep up to date records of locations and contact details to enable good communication prior to spraying operations. On many occasions we have rescheduled spraying on a certain day to allow chemically sensitive people to travel along roads knowing spraying will not be happening on the roadsides that day.
