The leaves of viburnum are again in the hole, as after the night Swedish table? It seems that the caterpillars again arranged a feast! We have collected understandable, tested methods from the channel “Garden-Ogorod with Veronika Polivkaina” on Dzen.ru (16+), helping to save Kalin without unnecessary nerves, without harm to nature and without expensive chemicals.
Mechanical methods are the first step to fight. The manual collection of caterpillars in a jar of soapy solution is effective with a slight infection. Cut the twisted leaves and branches with egg masonry and destroy them. Lay a film under the bush, shake the branches to shake the caterpillars, and remove them.
Folk remedies save with moderate defeat. Mustard infusion (100 g per 10 liters of hot water, insist 2 days) spray every 5-7 days. The soap-zero solution (300 g ash + 50 g of soap per 10 l of water) apply in the evening. A decoction of wormwood (1 kg per 5 l of water, boil for 30 minutes, dilute 1: 1, add 50 g of soap) also works.
With severe infection, chemical insecticides will help: “Aktara” (1 g per 10 l), “Inta-Vir” (1 tablet per 10 l) or “Karbofos” (60 g per 10 l). But do not use them during flowering so as not to harm bees, and stop the processing 30 days before the collection of berries. To restore damaged viburnum, cut the sick branches, feed urea (1 tbsp. L. by 10 l) and treat Epin (1 ampoule per 5 l).
