“…This concurs with previous research that showed seaweed extracts from A. nodosum could increase strawberry fruit yields by up to 30% (Spenelli et al 2010 ; Alam et al 2013 ; El-Miniawy et al 2014 ). In contrast, Boček et al ( 2012 ) showed that a mixture of seaweed extract and amino acids did not increase strawberry fruit yields in an organic system in Europe. The seaweed extract in the trial by Boček et al ( 2012 ), however, was only applied as a foliar treatment and was applied less frequently (five times through the cropping cycle) than in the current trial.…”

The increase in strawberry fruit yield by the seaweed extract in the current trial also increased revenue from fruit by 8% or AUS$0.30 per plant, which is a significant return for strawberry growers compared with the cost of the treatment.…”

The withdrawal of soil fumigants like methyl bromide is forcing strawberry growers to consider supplementary and alternative ways of producing crops. In addition to controlling soil-borne pests, soil fumigation causes an increased growth response in strawberry roots, and the use of biostimulants may offer an alternative to replace this response. We tested the hypothesis that treatment with a commercial extract (Seasol®) from the seaweeds Duvillaea potatorum and Ascophyllum nodosum can increase root growth, and transplant (runner) and fruit yields of strawberry. From 2014 to 2016, we conducted three field trials on strawberry farms in the nursery sector at Toolangi and in the fruiting sector at Coldstream in Victoria, Australia. We applied the seaweed extract as a monthly drench (10 L ha−1) to two cultivars of strawberry (‘Albion’ and ‘Fortuna’), compared with an untreated control. In the nursery sector, use of the extract significantly increased the density of secondary roots (feeder roots) on harvested runners by up to 22%. Treatment with the extract also significantly increased yields of marketable runners by 8–19%. In the fruit sector, use of the extract significantly increased the root length density (root length per volume of soil) of strawberry plants by 38% and marketable fruit yields by 8%. Root length density at final harvest and marketable fruit yield of strawberry were highly correlated (r = 0.94). This relationship provides an insight into the mode of action of seaweed extracts and is discussed. Overall, the results show the potential benefits of the integrated use of seaweed extracts in strawberry production across the nursery and fruit sectors, and their promise for supplementing or replacing the increased growth response provided by soil fumigants.

“…The obtained results from all variants were similar. Boček et al (2012) used commercial products Alginure (Tilco Biochemie GmBH, Germany), Myco-Sin® VIN (Dr. Schaette AG, Germany) and Polyversum ® (Biopreparaty Ltd., Czech Republic) and they observed lower occurrence of grey mould in majority variants in comparison with control. Using of apple tree wood chips for support of development microbial community in soil and plant debris, which could decrease level of occurrence of grey mould does not give positive results at least similar as give above-mentioned commercial products.…”

In the years 2014 to 2016 the influence of apple tree wood chips and composted apple tree wood chips in which oyster mushroom grew and yielded which were supplemented into soil on strawberry field production and occurrence of grey mould at strawberry (cv. 'Sonata') was evaluated. Average weight and number of fruits per plant, average fruit weight, average weight and number of fruits affected by Botrytis cinerea per plant, percentage of weight and number of fruits affected by Botrytis cinerea was calculated. There were recorded differences concerning strawberry yield among the investigated variants of plots, but mainly there were not statistically significant. In 2015 and 2016 the highest average weight of yield and the highest number of fruits was reached at plants cultivated on plots with apple tree wood chips. Average weight of yield on plots with apple tree wood chips was 663.72 g and 822.41 g in 2015 and 2016, respectively. Number of fruits per plant on plots with apple tree wood chips was 67.88 pieces and 65.29 pieces in 2015 and 2016, respectively. Occurrence of grey mould caused by Botrytis cinerea on all variants of plots was similar and small differences was found out only but statistically significant difference was among the years. Grey mould was the most frequently found out in the year 2016. B. cinerea affected 48.27, 56.89 and 55.94 grams of fruits per plant from plots with composted apple tree wood chips, plots with apple tree wood chips and control plots in 2016, respectively.

“…A number of merits can be mentioned in favour of biological insecticides, including neem and pyrethrum, in this respect: 1) the proved efficacy of the neem products under field conditions; 2) its environmentally friendly characteristics coupled with its harmless or minimal side-effects on the main natural enemies; 3) the great enthusiasm of the farmers for available inexpensive pesticide and their willingness to use it in their crop fields (El Shafie, 2001). 10 (Cholakov & Boteva, 2012) and those of Polyversum present mainly the fungicidal effect of the product (Gewehr, 2011;Boček et al, 2012). The most pronounced effect among organic products applied alone had foliar fertilizer Biofa based on algae extract that led to an increase by 9.8% on average over the control.…”

The possibilities for increasing the productivity and control of the pea weevil (Bruchus pisorum L.) in field pea (Pisum sativum L.) organic cultivation by the use of following bioproducts NeemAzal T/S and Pyrethrum FS-EC (insecticides), applied individually and in combination with Polyversum (growth regulator and fungicide) and Biofa (foliar fertilizer), as well as to evaluate the stability of the used mixtures were studied. Synthetic products Nurelle D and Flordimex 420 (alone and in combination) were used as a standard. The products were applied once (at budding stage) or twice (at budding and flowering stages). The results showed that forage pea productivity was influenced positively by the application of all organic products. The plants treated with the organic combinations formed an average yield of 3190.2 kg/ha, which was only 4.7% lower than that for the synthetic combination of Flordimex+Nurelle D. The highest yield was produced under application of two mixtures: Biofa+Pyrethrum and Polyversum+Pyrethrum at budding and flowering stages (22.0 and 21.8% above untreated control, respectively). These combinations were also distinguished for their most pronounced protective effect against the attack of the pea weevil and decrease in its numbers of 37.0 and 38.5%, respectively. Pyrethrum was distinguished for a lower degree of damaged seeds and a toxic effect against the pea weevil in comparison with NeemAzal. Technologically the most valuable variant, which united high stability, productivity and protection against pea weevil, was the combination of Biofa+Pyrethrum applied twice. Further investigations are indispensible to expand the range of products (bioinsectides, biofertilizers and growth regulators), which provides good insect control and high productivity in pea organic farming conditions. Additional key words: organic products; productivity; pea weevil control; stability.
