“…Fungicides. The warm, high relative humidity and windfree condition in greenhouse support fungal growth on leaves and dispersal in the air (Hala si et al 2008). Hence, farmers need to prevent an outbreak of fungal diseases.…”

Aquaponics has the potential to produce sustainable, high‐quality food through integration of hydroponics and aquaculture, but its commercialization is stalled by bottlenecks in pest and disease management. We reviewed integrated pest and disease management steps and techniques in hydroponics to qualify as suitable techniques for different aquaponic designs. Non‐chemical prophylactic measures are highly proficient for pest and disease prevention in all designs. Still, the use of chemical control methods remains highly complicated for all systems. We simulated 10–20% runoff concentrations of 9 pesticides in the common UVI design and compared them with NOEC, LC50 of fish. Endosulfan seems most toxic with runoff AI (20.7 μg L−1) exceeding LC50 (10.2 μg L−1) and NOEC (0.05 μg L−1). At 20% runoff, most chemical pesticides pose risks in aquaponic systems. Natural pesticides were also discussed as potential alternatives with low acute toxicity to fish, but little is known about their effects on water and bacteria. While insecticides and herbicides are replaceable by well‐established commercial biocontrol measures, fungicides and nematicides would still be relevant in aquaponics due to low efficiency of alternatives (e.g. natural enemies, entomopathogenic fungus). Monitoring and cultural control are the first approaches to contain pest population below the action threshold. Biological controls, in general, are adaptable to a larger extent. Further studies are required on how to utilize indigenous microbial community in aquaponics (dominated by Proteobacteria; effective at ~103–109 CFU mL−1) as a frontline defence.

“…Lettuce Lactuca sativa (Asteraceae; Compositae) is one of the World's most important salad crops and horticulturists regard it as one of the most profitable to grow [1]. Leaf, stem, root and seed infections caused by systemic B. cinerea are common in lettuce grown in the whole of the UK [2], Infection of lettuce plants by B. cinerea is favoured by cool moist weather conditions [3,4]. However, the levels of disease in crops can alter from year to year, with the cost of losses in winter lettuce estimated at £257 million due to B. cinerea infection alone in fungicide-treated crops [5].…”

“…Symptom development in the fields with no previous record of lettuce cropping can arise from the sowing of infected seed or by infection from air-dispersed spores. Once infection is established in a crop, the infected lettuce plants show abundant white, cottony mycelial growth and hard, black sclerotic bodies on the underside of the lower leaves and the basal part of the stem [4]. The head and stem of infected plants often disintegrates into a soft watery mass covered with sclerotia [8].…”

Studies showed that both airborne seed infection of B.cinerea have been implied as major sources of primary inoculum in different part of lettuce plant. Results from quantitative real-time PCR and visual observations showed that seed infection was the main source of inoculum in the field trial conducted in this study. However, glasshouse studies established that the pathogen can be transmitted from infected seeds into roots, shoots and leaves without showing symptoms. Plants in the field trial remained free of infection for approximately four months before symptoms were observed in the crop. Covering the crop during part of the growing season was found to prevent the growth of the pathogen, despite the use of infected seed, which indicate that changes in the physiological condition of the plant and/or environmental conditions most especially over watering may trigger disease development. However, once the disease symptoms appeared in the field it quickly spread throughout the plants. Level of inoculum equivalent to spore concentrations between 30 and 60 spores per m 3 of air was only detected on three occasions during the growing season. The temporal pattern and level of detection of B. cinerea DNA in spore tape samples indicated that airborne inoculum was limited and most likely represented rain-splashed conidia rather than putative ascospores.
