Embodiment 1

[0014] For more than 3 years of growth, a large area covered with shrubs and grass, and the coverage is greater than 60%, the non-directional spraying method is used to evenly spray the liquid medicine on the stems and leaves of the five-clawed dragon, and the application rate is 30g / mu. The number of times is 3 times.

Embodiment 2

[0016] For the growth of less than 2 years, a large area covered with shrubs and grasses, and the coverage is less than 60%, use the directional spray method to spray the stems and leaves of the five-clawed dragon directly and evenly, the application rate is 15g / mu, and the number of spray 2 times.

Abstract

The invention discloses an ipomoea cairica chemical preventing and removing method which imposes herbicide on the ipomoea cairica to prevent and remove the ipomoea cairica. The herbicide is a mixed reagent of Londax and acetochlor with a ratio of 6:1-3:1. The method of the invention can effectively remove the ipomoea cairica and can prevent the regrowing of the ipomoea cairica.

Description

technical field [0001] The invention relates to the field of harmful plant control, in particular to a chemical prevention and control method of Auranthus quinquefolium. Background technique [0002] Ipomoea cairica (Ipomoea cairica) is a perennial herbaceous vine of Convolvulaceae (Convolvulaceae). It is native to North America and is now widely distributed in tropical and subtropical regions. Ipomoea cairica is usually propagated by seeds. It is easy and grows rapidly, but in Guangdong, it only blooms and rarely bears fruit. It mainly uses stems for asexual reproduction, and it can grow vegetatively throughout the year. The entwined stem of the five-clawed golden dragon has a strong climbing ability. It climbs up the trunk and quickly occupies the periphery of other plants, densely covering the crown of the tree, so that the covered plants cannot get enough sunlight and die. It is extremely harmful to green plants, especially garden plants. In recent years, the five-claw...
