Many commercial farmers doing ORGANIC farming uses Residue-free fertilisers, Bio-Fertilisers, Bio-pesticides and bio-chem products. The terms organic or organically grown indicate that the food has been produced without synthetic pesticides and also without synthetic fertilizers and certain other chemicals that are common in conventional, industrialized agriculture. Food labeled certified organic has been independently verified to be produced to organic standards. The term pesticide-free has no precise meaning, and food with that label may be any of several types. It might have been grown without pesticides, similar to organically grown food, but not grown organically in other ways. It might have been tested before it reached the market and certified to contain no detectable pesticide residues. Unfortunately, none of these labels guarantees that the food contains no pesticide residues. While synthetic pesticides are prohibited in organic farming, some natural pesticides may still be used, and they are not necessarily less worrisome just because theyre natural. Some organic food may also be contaminated at low levels with pesticides blown in from adjacent farms or left in the soil from past use. Pesticide-free food has the same problems, and even if tested for residues, it may contain pesticides below the detection limits of the tests used or ones not on the relatively short list of pesticides that the analysis tests for. But despite these caveats, organically grown food generally does contain significantly lower pesticide residues than does conventionally grown food, and food with a no pesticides claim often has more residues than organic food but less than conventionally grown food.
