Until recently, we separated farmers and urban communities. Each had their own ministries, policy plans, cultures, knowledge and education institutes and even political parties. Now we accept that this division is gone in the Netherlands. Rural areas ceased to exist, and urbanity was found everywhere. Former rural areas were transformed into green spaces inside metropolitan areas. Farmers and peaceful villages woke up and saw themselves surrounded by cities. Even more: city dwellers became their neighbours. The time has come that we look upon farming and urbanised areas as an integrated system.

Active antifungal packaging is a technological solution for reducing the postharvest losses of fruits and vegetables associated with phytopathogens. Anthracnose (Colletotrichum gloeosporioides) is the principal fungus that causes post-harvest avocado fruit decay. In this study, antifungal sachets filled with oregano oil-starch capsules were prepared, and their active effects were demonstrated on Hass avocado fruits. Oregano oil (31 % of carvacrol) was encapsulated with corn starch by spray drying. Tyvek sachets (4 × 4 cm) filled with 80 (T1) and 160 mg (T2) of oregano oil-starch capsules (99.35 ± 1.86 mg g − 1) were fabricated. The antifungal effects of the sachets were tested in vitro and in vivo using a humidity chamber (90–95 % relative humidity (RH)) on fruits inoculated with anthracnose. The results showed that T1 and T2 inhibited 75.21 ± 2.81 and 100 % in vitro growth of anthracnose at 25 °C for 12 days. Furthermore, Hass avocado fruits stored in a humidity chamber at 25 °C for 6 days showed that only T2 significantly (p < 0.05) reduced the area of lesion produced by artificial inoculation of Hass avocado fruits with anthracnose. On average, the lesion area in the Hass avocado fruits treated with T2 was 13.94 % smaller than that in the control fruit.

The aim of the present work was to control phytopathogens associated to mango decay by exposure to antifungal thyme oil-starch/agave fructans microcapsules in Nylon sachets. Fusarium pseudocircinatum, Alternaria alternata, Neofusicocum kwambonambiense, Cladosporium pseudocladosporioides, and Colletotrichum gloeosporioides were isolated from mango fruits and its mycelial growth was 100% inhibited with 5 μL of thyme oil. Thyme oil was microencapsulated with modified starch/agave fructans by spray drying. Thymol content, size, and shape of microcapsules were evaluated. Antifungal sachets were prepared by filling Nylon bags (4 × 4 cm) with different doses of thyme oil microcapsules: 0.10, 0.15 and 0.20 g. The mycelial growth of all microorganisms was controlled with 0.10, 0.15 and 0.20 g of antifungal sachets. The incidence (75 and 65%) and severity (77 and 41%) of C. gloeosporioides were effectively reduced in mango, respectively, using 0.10 and 0.20 g of antifungal sachets.
