Pesticides are used in all agricultural and horticulture systems and plays a key role to diminish environmental threats and also health perils. To diminish pesticide uses is a stimulating in an orchards where recurrently pesticides are used so as to control abundant pests and also diseases, but it may be vital to increase a fruit production and its sustainability. Agronomic researches had provided changes to control chemical for the organization for a single pest or disease, but had been seldom addressed for the design of an overall justifiable policies for aiming to reduce pesticide uses. New insights are permitted by the system are now developing. Here, we are reporting the level of pesticide use and also the agro-environmental performances of the three protection systems to an apple orchards gaged from 2005 to 2008: (i) unoriginal, (ii) low input and (iii) biological farming. To measure the significances of the cultivator in order to decreasing pesticide uses, these safeguard systems were combining with three cultivars different in scab susceptibility: ‘Ariane’ (Vf-resistant), ‘Melrose’ (low-susceptibility) and ‘Golden Delicious’ (susceptible). Thus, nine ‘management x cultivar’ apple plantation systems are to be assessed. The level of pesticide uses are now highest in conservative ‘Golden Delicious’ and in ‘Golden Delicious’ plots for their protection system. A 43-56% decline in pesticide uses were observed in ‘Ariane’ and ‘Melrose’ in both for low input and also organic framings defense system as compared to conventional ‘Golden Delicious’ as orientation. Only with low input ‘Melrose’ and also low input ‘ARIANE herbicide’ achieved a Good level of production and less fruit damages similar to the matching conventional cultivators under reduced pesticide uses, also allowing reduced on environmental impacts. But even with the low input ‘Melrose’ and least pesticide-dependent systems were far from being pesticide-free, suggesting that the current straight-designed mono-clone plantations are to be hardly appropriate to drastically reduce pesticide use and that the range of commercial apple cultivators should be renewed to offer more robust cultivators.
