Presto

Dual-action pest control: why choose Presto

In modern crop production, where pest resistance to single-active ingredient products is a growing challenge, combined insecticides take center stage. Presto, produced by Hangzhou Ruijiang Chemical Co., Ltd., is a systemic insect-acaricide that merges two powerful active ingredients: clothianidin and lambda-cyhalothrin.

Technological advantage of the composition

The synergy between these two components allows for the effective control of a broad spectrum of insects. Clothianidin, a neonicotinoid, provides prolonged systemic protection: the product enters plant tissues, making them toxic to sucking pests like aphids and leafhoppers. Meanwhile, lambda-cyhalothrin provides an immediate knockdown effect, disrupting the nervous system of pests upon contact.

Field application practices

• Target crops: The product has proven highly effective in potato fields and winter wheat crops.
• Target pests: Major targets include the Colorado potato beetle, the sunn pest, cereal leaf beetles, as well as various aphids and leafhoppers.
• Regimen: The product is supplied as a suspension concentrate. Application rates range from 0.2 to 0.5 l/ha, depending on the phytosanitary situation.

A key aspect is its systemic mode of action, which helps protect even those parts of the plant not directly hit by the spray. Users should note the product's hazard class (Class 3) and adhere to the guidelines: no more than two applications per season, with a pre-harvest interval of 20–30 days. It is an optimal solution for farming operations aiming for consistent yields without the extra costs of repetitive treatments.
