This post if for all you commercial LCO's. I think in today's society it is just a matter of time where spraying for dandelions and other broadleaf weeds for cosmetic reasons will be outlawed. Do you honestly think that organic methods can be used commercially and still be reasonably cost effective? Or do you think people will have to look at dandelions in a different perspective? Or will they have to put there money where their mouths are if they want to go "green" I know some will say Corn Gluten. But this is expensive and has to be put down at very specific times and is also rain sensitive. I mow 400 acres per week and @ 20 pounds per 1000 square feet that is alot of meal. Over seeding @ $124 per 50 kilo bag of grass seed is also very expensive plus labor to put it down. The reason I say commercial is because we do shopping centres, business parks, Schools... ALot of times there is irrigation but it is limited or cannot be on city property that the mall owners are responsible for. What about the city land beside you that is covered with dandelions or thistle can organic practices be effective when that is beside you? We are certified pesticide applicators but only do our own commercial accounts. I got a quote from a company to do some organic weed control here are the figures that they quoted. Spring spaying of liquid corn gluten $2700 Summer spraying of beet extract $2700 Fall spraying of beet extract $2700 Total $8100 This was for 4.3 acres and all three spraying must be completed to maintain a 75% effective weed control compared to conventional spraying. Same area same company for conventional spraying was one application @ $728. I know that organic methods can be effective residential lawns just because I feel there can be more control and you also have an owner who will be more involved if they want organic. My question for you is " Do you think going organic is realistic commercially? Or are the Costs going to be so high that there are going to be weeds every where?
