ABSTRACT.
Low fruit set is one of the main factors leading to low yields of the pear orchards in Brazil. Exogenous application of plant growth regulators (PGRs) shows great potential to overcome this problem. Recent studies have shown great promise of several ethylene inhibitors in increasing fruit set and yields of several fruit species. The objective of this study was to evaluate the effect of several PGRs sprayed at different timings on fruit set, yield, and fruit quality of 'Rocha' pear in southern Brazil. The study was performed during the 2016/2017 growing season using five-year-old 'Rocha' pear trees on 'BA29' quince rootstock. Treatments consisted of an untreated control, aminoethoxyvinilglycine (AVG) 60 mg L‑1 applied 1+2 weeks after full bloom (WAFB); cobalt (Co) 25.6 mg L‑1 + molybdenum (Mo) 38.4 mg L‑1 sprayed at full bloom (FB), 1 WAFB, 2 WAFB, 1 + 2 WAFB or FB + 1 + 2 WAFB; and kinetin (Ki) 0.18 mg L‑1 + gibberellic acid (GA3) 0.1 mg L‑1 + indolebutyric acid (IBA) 0.1 mg L‑1 sprayed at FB or FB + 1 WAFB. Fruit set, number of fruit tree‑1, yield, average fruit weight, fruit length (L), fruit diameter (D), L/D ratio, seed number, flesh firmness and soluble solids content were assessed. Fruit set and yield were increased by all treatments except Ki + GA3 + IBA sprayed at FB in total number of fruit at harvest, number of thinned fruit and yield compared to control trees. The greatest increase in yield was observed with AVG. Average fruit weight of all treatments, except Co + Mo (FB), was reduced compared to control trees, likely due to the increased crop load.

ABSTRACT. - Citrus sour rot caused by Geotrichum citri-aurantii is one of the most important postharvest diseases in citrus fruit, causing huge economic losses. Traditionally, it has been controlled by the postharvest application of guazatine and propiconazole fungicides, but restrictions in their use make it urgent to find an alternative for sour rot management. Natamycin, a common food preservative, and the organosulfuric compounds extracted from Allium species are safe food additives that control different foodborne pathogens. In the present study, the curative activities of commercial formulations of natamycin (Fruitgard Nat 20) and an Allium extract (PTSO: propyl thiosulfinate oxide; Proallium FRD®), were evaluated for the control of G. citri-aurantii in artificially inoculated lemon fruit. Trials in laboratory and in commercial conditions were carried out to explore the feasibility of including both compounds as part of a safe postharvest sour rot disease control strategy. Under controlled laboratory conditions, sour rot was significatively reduced by 500 mg L−1 of natamycin, 580 mL L−1 of PTSO and 290 mL L−1 of PTSO + 4% of a food coat, applied by immersion. Nevertheless, the maximum dose of PTSO (580 mL L−1) caused phytotoxicity on the fruit rind. In commercial drenching conditions, 290 mL L−1 of PTSO + 4% of a food coat reduced sour rot incidence similar to conventional treatment. In a packing line treatment, spray application of 500 mg L−1 of natamycin with a previous dip in sodium bicarbonate, resulted in nearly 70% reduction of disease incidence compared to conventional salt application. A second commercial experiment revealed that fruit drenching with 290 mL L−1 of PTSO + 4% food coat followed by an in-line cascade application of 500 mg L−1 of natamycin is completely effective for sour rot control after 20 days at 5 °C. Further exposure at room temperature for 7 d showed a 61% reduction in sour rot incidence compared to the control. Results revealed that natamycin and PTSO are promising tools for sour rot control used alone or combined as part of an integrated postharvest strategy. © 2022 Elsevier B.V.
