Abstract
The invention relates to the field of farm chemical weed killer, and particularly discloses a compound agent and a preparation method and application for preventing and killing off aquatic weeds in a sea cucumber culture zone. The compound agent for preventing and killing off the aquatic weeds in the sea cucumber culture zone comprises, by weight, 5-90% of prometryn, 0.5-5% of bensulfuron methyl, 5-10% of fatty alcohol-polyoxyethylene ether, 1-5% of lauryl sodium sulfate, and the balance of filler. The compound agent and the preparation method and the application for preventing and killing off the aquatic weeds in the sea cucumber culture zone have the advantages that two different machine-made agents are compounded, the dosage of one agent can be reduced, safety and resistance postponing of the aquatic weeds are benefited, effects of preventing and killing off the aquatic weeds are greatly improved, high efficiency, economical performance and time and labor saving are achieved, operating performance is strong, operation is rapid and thorough, and spirogyra and other weeds in the sea cucumber culture zone can be safely and effectively prevented and killed off to avoid severe even destructive damage to sea cucumbers.
Description
(1) technical field
The present invention relates to the pesticide herbicide field, particularly a kind of compound drug and preparation method and application that prevent and kill off culturing sea cucumbers district aquatic weed.
(2) background technology
The sea cucumber meat is soft tender, and is nutritious, is typical high protein, low fat food, and the flavour fat is beautiful, and local flavor is graceful, is the name food delicacies that has long enjoyed a good reputation.Modern study shows, sea cucumber has the memory of raising, delay the sexual gland aging, prevent arteriosclerosis and the effect such as antitumor.In recent years, the China coast beach is risen on the way and is built in a large number pool cultivated sea cucumber, has a extensive future.Generally speaking; gather in the crops the time in 2～3 years of sea cucumber needs season; in the holothruian cultures process; usually can occur the aquatic weeds windings such as a large amount of seawater continuous Spirogyracommunis, hydrodictyon reticulatum Hydroaictyon reticulatum in the culturing sea cucumbers district wraps around sea cucumber; polluted source not only; also severe inhibition the growth of sea cucumber, hinders the sea cucumber results, even also can cause the sea cucumber total crop failure.
The single dose of prometryn Prometyrn, bensulfuron-methyl bensulfron-methy is general in existing technology only to be used for dry land and agent for removing grass in paddy field, and is not useful on relevant report or the patent information of preventing and kill off culturing sea cucumbers district aquatic weed.Paddy field chemical weed control method is applied mechanically in some holothruian cultures district simply, abuses the medicine drug abuse, and bad poisoning appears in result again and again, directly causes the sea cucumber underproduction even total crop failure, and the herbicidal effect that has is not good enough.It is not only time-consuming but also not thorough manually to prevent and kill off culturing sea cucumbers district aquatic weed, has directly limited the development of holothruian cultures.
(3) summary of the invention
The present invention provides a kind of high-efficiency and economic, saving of work and time, strong operability, quick compound drug and the preparation method and application that prevent and kill off thoroughly, safely and effectively culturing sea cucumbers district aquatic weed in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of compound drug of preventing and kill off culturing sea cucumbers district aquatic weed, made by the component of following percentage by weight: prometryn 5～90%, bensulfuron-methyl 0.5～5%, fatty alcohol-polyoxyethylene ether 5～10%, lauryl sodium sulfate 1～5%, surplus are filler.
Preferred prometryn and bensulfuron-methyl weight ratio are 15: 1 in the such scheme.
Described filler is diatomite.
The preparation method that this prevents and kill off culturing sea cucumbers district aquatic weed compound drug comprises the steps:
With prometryn and bensulfuron-methyl mechanical mixture 30-60 minute, then add fatty alcohol-polyoxyethylene ether, lauryl sodium sulfate and filler and proceed mechanical mixture, mixing 30-60 minute laggard promoting the circulation of qi stream pulverizes, and then carry out secondary mechanical and mix, mix and detect the qualified compound drug that this prevents and kill off culturing sea cucumbers district aquatic weed that namely gets after 30 minutes.
Described filler is diatomite.
The formulation of compound drug of the present invention is wetting powder.
This prevents and kill off culturing sea cucumbers district aquatic weed compound drug in the application of culturing sea cucumbers district aquatic weed control.
The present invention prevents and kill off the compound drug of culturing sea cucumbers district aquatic weed and preparation method and application's beneficial effect is: with the composite reagent of two kinds of different mechanisms, can reduce a kind of consumption of medicament, help safety and the resistance that delays aquatic weed, greatly improve the effect of aquatic weed control, high-efficiency and economic, saving of work and time, strong operability, fast thoroughly, can prevent and kill off safely and effectively culturing sea cucumbers district maritime interior waters silk floss waits weeds that sea cucumber is carried out serious even crushing harm.
(4) embodiment
