Problems solved by technology

However, it is obvious that the environmental problems after water hyacinth dies and rots have not been resolved. At the same time, sulfonylurea herbicides are high-residue herbicides, which are likely to bring negative impacts on the environment.

Embodiment 6

[0024] According to the formula of Example 1, that is, the weight contents of mepipeperamine, ammonium glyphosate, SDP and NaCl are respectively 1%, 29%, 5% and 65%, and the drug efficacy test is carried out. The experiment set up CK (control) and 6 drug treatments. Among them, treatment 1 and treatment 2 are the preparations of the present invention, and the dosages are 100 g / mu and 50 g / mu respectively. Treatments 3-6 were other low dose single doses. Medication on October 29, 2002. figure 1 is the number of tillers per water hyacinth plant measured 29 days after application.

[0025] from figure 1 Look, for CK, the number of tillers of a single water hyacinth changed from 0 to 5 within 24 days (October 29-November 21), showing its strong tillering ability. The number of tillers in treatment 1 was always lower than that of other treatments, and the tillering rate was controlled to 70%, and remained stable for a long period of time. The number of tillers controlled by tr...

Abstract

A common water hyacinths asexual propagation inhibitor comprises (a)DPC (b)Glyphosate and its salt (c)agricultural adjuvant SDP of plant source (d)NaCl as effective constituent. The said effective constituents is mixed according to a suitable proportion, which can control the common water hyacinths asexual propagation and vegetative growth on the premise that common water hyacinths don't die and decay. The inventive inhibitor has low toxicity, low residue, can control the common water hyacinths population development and endanger.

Description

technical field [0001] The invention relates to an inhibitor for controlling the asexual reproduction and vegetative growth of water hyacinth, which can effectively control the development of its population without causing the water hyacinth to die and rot. It belongs to the field of environmental protection and pest control. Background technique [0002] Water hyacinth is a common name for water hyacinth (Eichhornia crassipes). Originating in South America, it was introduced into my country as feed in the 1950s because of its rich nutrients. However, this weed has a very strong asexual reproduction ability, and its population can increase the biomass by 20-30% every day under suitable conditions. A large number of water hyacinths cover the water surface, which will cause the deterioration of the water body environment, lead to the reduction of aquatic organisms, and block the river and hinder navigation. Therefore, it is currently recognized as one of the world's top ten...
