Abstract
From 2006-2007 to 2009-2010 field trials with non-chemical alternatives have been conducted in the Experimental Farm El Cebollar (IFAPA) (Moguer-Huelva, Spain). Complete randomized blocks with 4 replications (150 plants/rep.) and 8 treatments were used.
Fumigant poultry manure was applied every second week of July and soil solarization with low density polyethylene (LDPE) transparent film was applied from mid-July to mid-August, annually.
In 2006-2007 and 2007-2008 the treatments applied were: A: untreated control; B: biosolarization with fresh poultry manure (30,000 kg/ha); C: biosolarization with dry poultry manure (30,000 kg/ha); D: Trichoderma spp. (Tusal®, Newbiotechnic, S.A.); E: treatment B implemented with foliar Harpin 3% protein (Messenger®, Eden Bioscience); F: treatment B implemented with biostimulant (Papillon Complex®, Coferal); G: treatment B implemented with quitosane (Puxa®, Coferal); H: treatment B implemented with Trichoderma spp. (Tusal®). Treatments A and D (without soil solarization) showed the lowest yields.
Moreover, treatments E, F, G and H (implemented biosolarization) did not improve yield of basic biosolarization treatment (B). In 2008-2009 the treatments applied were: A: untreated control; B: biosolarization with fresh poultry manure (30,000 kg/ha); C: biosolarization with dry poultry manure (30,000 kg/ha); D: biofumigation with fresh poultry manure (30,000 kg/ha), without soil solarization; E: biosolarization with fresh poultry manure (15,000 kg/ha); F: biosolarization with fresh poultry manure (7,500 kg/ha); G: biosolarization with Brassica pellets (2,000 kg/ha) (Biofence®, Triumph Italia of Cerealtoscana Group); H: biofumigation with Brassica pellets (2,000 kg/ha). Again, treatments without soil solarization A, D and H showed the poorest pathogen control and the lowest yields.
Treatments B and E and G showed the highest yield.
In 2009-2010, new treatments were applied including other biofumigants, namely sugar beet vinasses and glycerin.
The presence of dead plants during the second part of the growing season (April-May 2010) was very high and much earlier than former growing seasons, with significant differences among treatments, Fusarium oxysporum and Macrophomina phaseolina were identified mainly.
Our four-year results suggest that biosolarization with fresh poultry manure and with Brassica pellets would be a good solution for non-chemical soil fumigation in the case of the strawberry cultivation.
