“…No differences among spray systems were found on arthropods occurring in vineyards highlighting that FSSs are efficient as standard methods for insecticide application against leafhoppers, which are major grapevine pests [27][28][29], and no differences on side-effects on beneficial predatory mites emerged [30].…”

Modern viticulture cannot be practiced without the use of plant protection products to control diseases like downy mildew, powdery mildew, and pests. In severely sloping vineyards, where mechanization is not possible, pesticide application is realized using spray guns, which is a laborious, expensive, and dangerous application technique. In these vineyards, where viticulture is defined as “heroic viticulture,” vine-growers could seriously take advantage of innovation in spray-technique applications. For this reason, several prototypes of a fixed spraying system (FSS) were realized in recent years. Two prototypes of a fixed spraying system were built in 2019 in two different vineyards in the Veneto region (north-eastern Italy). In both vineyards, the fixed spraying systems were used to perform pesticide application during the 2020 season to control downy mildew, powdery mildew, and pests. With this solution, both vineyards were successfully protected, resulting in comparable infection degrees and yields as the ones protected with airblast sprayers and spray guns. This study contributes to assert fixed spraying systems as an innovation that could improve working conditions, safety, timing, and performances of plant protection products’ application in heroic viticulture areas.

“…In vineyards, kaolin was effective against sap-sucking pests, such as the leafhoppers Hebata vitis (Göthe) [ 9 ] [syn. Empoasca vitis (Göthe)], Zygina rhamni Ferrari, Arboridia kermanshah Dlabola, Erasmoneura vulnerata (Fitch) and Scaphoideus titanus Ball [ 10 , 11 , 12 , 13 ], the grape phylloxera Daktulosphaira vitifoliae (Fitch) [ 14 ] and the vine cicada Psalmocharias alhageos [ 15 ], as well as carpophagous pests, such as the European grapevine moth Lobesia botrana (Denis and Schiffermüller) [ 16 , 17 ] and the spotted wing drosophila Drosophila suzukii Matsumura [ 18 ]. Kaolin provided an effective control of two polyphagous scarab beetles Macrodactylus subspinosus (Fabricius) and Popillia japonica Newman, feeding on grapevine leaves and bunches [ 19 , 20 ].…”

In vineyards, kaolin application and bunch-zone leaf removal (LR) were effective in the control of leafhoppers and Lobesia botrana, but their side effects on generalist predators are still poorly understood. In north-eastern Italian vineyards, the impact of kaolin and LR on species and functional diversity of spiders, as well as the abundance of spiders and generalist predatory insects, was assessed in one vineyard for two consecutive years and in two vineyards for one year. The ecological indices of the spider community were never influenced by kaolin and only in one case were they influenced by LR. At the spider family level, kaolin reduced the abundance of Araneidae, Oxypidae and Salticidae, but only in single cases. In single cases, kaolin reduced the amount of Orius sp. anthocorids and increased that of Scymninae coccinellids, whereas LR increased the amount of Aeolothrips sp. Moderate use of kaolin and the application of LR had negligible and inconsistent impacts on generalist predatory arthropods in vineyards and was therefore compatible with IPM strategies.

“…The efficacy of pyrethrins confirms previous trends [ 32 , 39 , 40 ]. Results obtained using kaolin (54.2% of efficacy) stress its potential as a complementary tool against several leafhoppers included S. titanus [ 33 , 46 ]. Efficacy levels of pyrethrins increased when the adjuvant Mago was added in the trial with sampling on basal leaves (from 66.6% to 70.8%) and, even if only on average, in the trial with sampling on suckers (from 81.0% to 89.5%).…”

Scaphoideus titanus is the main vector of phytoplasmas associated with Flavescence dorée (FD), one of the most serious threats to viticulture in many European countries. To minimize the spread of this disease, mandatory control measures against S. titanus were decided in Europe. In the 1990s, the repeated application of insecticides (mainly organophosphates) proved to be an effective measure to control the vector and the related disease in north-eastern Italy. These insecticides and most of the neonicotinoids were recently banned from European viticulture. Serious FD issues detected in the recent years in northern Italy could be related to the use of less effective insecticides. Trials aimed at evaluating the efficacy of the most used conventional and organic insecticides in the control of S. titanus have been performed in semi-field and field conditions to test this hypothesis. In efficacy trials, carried out in four vineyards, etofenprox and deltamethrin proved to be the best conventional insecticides, while pyrethrins were the most impactful among organic insecticides. Insecticide residual activity was evaluated in semi-field and field conditions. Acrinathrin showed the most significant residual effects in both conditions. In semi-field trials, most of the pyrethroids were associated with good results in terms of residual activity. However, these effects declined in field conditions, probably due to high temperatures. Organic insecticides showed poor results in terms of residual efficacy. Implications of these results in the context of Integrated Pest Management in conventional and organic viticulture are discussed.
