No, a lawn that is located next to organic crops cannot be sprayed with pesticides. To be in compliance with organic certification guidelines and inspections, pest control must be animal- or plant-derived, such as pyrethrin from Chrysanthemum cinerariifolium, and therefore tends to involve botanicals, horticultural oils and insecticidal soaps. There tends to be a concern over drift since even the slightest breeze can carry pesticide drops and particles away from the target area.
So insects won't eat the crops.
A sprayer is a device used to spray a liquid. It can be used in agriculture, a sprayer is a piece of equipment that spray nozzles to apply herbicides, pesticides and fertilizers to agricultural crops.

All plants have the potential to be organic. For something to be described as organic is must be grown without the use of pesticides, insecticides, growth hormones or GMO's, basically it must be grown without chemicals. As long as you do not spray the plants in you planter with pesticides/chemicals, do not use chemicals in the soil they are planted in, then they should be considered organic. However the standards for being registered as an organic farmer are much more complex and require certification through the USDA showing that the food being grown complies with the legal regulations.
