Grazers G4 Lily Beetle Concentrate 350ml

The lily beetle (Lilioceris lilii) is the number one pest of lilies. It can reduce a lily plant to nothing in just a few days. Both the adult lily beetles and the horrible grubs devour lilies – leaves, flowers and flower buds.

Adult beetles about 5-8mm (about 1/4in) long, bright red with a black head and legs emerge from the soil from late March to May, laying eggs from April until September. They overwinter in sheltered places, often in the soil but not always near lilies. Eggs are laid on the underside of leaves in groups of up to 12-15; they vary in colour from bright orange to nearly red. The grubs have dirty orangey bodies and cover themselves with their own excreta; this gives them some protection and they can be mistaken for birds’ droppings. They then fall onto the ground and pupate.

G4 ECO is an easy-to-use spray which coats the leaf and while being effective against damage also benefits the plant due to its unique formula. When sprayed proactively every 7-10 days upon first sighting (from March onwards depending on the region and climate) plants continue to thrive, eggs are less likely to be laid. Therefore larvae aren’t a problem either.
