Abstract

The invention discloses a liquid formulation for trunk injection contained with extract of willow root for landscape plant insect attack and preparation and application thereof. The liquid formulation for trunk injection for landscape plant insect attack comprises the extract of the willow root, emamectin benzoate, surface active agent, anti-decomposing agent and cosolvent. The mass percents of the extract of the willow root, the emamectin benzoate, the surface active agent, the anti-decomposing agent and the cosolvent are 4 to 20%, 0.75 to 1.5%, 1 to 10%, 0.35 to 0.5% and 10 to 20% in sequence, and the margin is water. The liquid formulation for trunk injection for landscape plant insect attack is contained with the extract of the willow root, the insecticidal spectrum is wide, and the functional mechanism is unique, so that the drug resistance of the injurious insects can be solved effectively, features of contacting toxicity, stomach toxicity, systematic action and the like are possessed, drug application is conducted in an anhydrous and non-contact mode, the liquid formulation is safe to human and environment, and purposeful prevention and cure on the injurious insects like hemiptera, coleoptera, homoptera, diptera and some of lepidoptera at the places of forests, urban gardening, gardening trees in a scenic spot, border trees and protection forest are achieved.

Description

technical field [0001] The invention relates to the technical field of prevention and control of garden tree pests, in particular to a garden plant insect pest injection dry solution containing the root extract of willow bark and its preparation and application. Background technique [0002] Environment and development are major issues of global concern. Protecting the ecological environment and achieving sustainable development are directly related to the destiny and future of mankind. At present, large and medium-sized cities and urbanized townships are paying more and more attention to urban greening, and the per capita green area has been significantly increased. While landscaping brings residents a high-quality living space, the chemical pesticides used in maintenance management to prevent and control diseases, insects, and weeds also have a negative impact on the urban environment. As long as the landscaping area is larger, the pesticide pollution will be more serious...
