Drug for controlling rust disease of populus euphratica and preparation method of drug

Abstract

The invention discloses a drug for controlling a rust disease of populus euphratica and a preparation method of the drug. The drug comprises red willow leaves and / or immature stems, triadimefon or tebuconazole, urea and water. The use efficacy of triadimefon or tebuconazole is improved by the aid of a cosolvent, meanwhile, the capability of the populus euphratica for relieving infection of the rust disease is improved, and the growth potential of the populus euphratica is promoted. The red willows are naturally not infected with the rust disease, so that an environment unfavorable to the rust disease can be formed; meanwhile, soup cooked with the red willow leaves and / or immature stems is slightly acidic, and dissolving of triadimefon or tebuconazole can be facilitated; the urea can supply nutrition to the populus euphratica, and the growth potential of the populus euphratica is promoted. Therefore, the soup cooked with the red willow leaves and / or immature stems is mixed with 15% triadimefon wettable powder and 25% pentazole wettable powder, the mixture is mixed with the urea and sprayed to the populus euphratica, and the rust disease of the populus euphratica can be controlled. Material resources are environment-friendly, the preparation is simple, the use effect is remarkable, and no phytotoxicity is generated.

Description

technical field [0001] The invention relates to the technical field of tree disease prevention and control, in particular to a medicine for preventing and treating Populus euphratica rust and a preparation method thereof. Background technique [0002] Populus euphratica rust is one of the important diseases of young Populus euphratica forests and seedlings. Because Populus euphratica currently uses seeds to raise seedlings, the seeds are collected in the same year and immediately sowed. The seedlings encounter uredia spores on the big trees as soon as the true leaves emerge, and the disease is serious. According to the survey of forest farms of the 29th regiment in Korla, Xinjiang, the incidence rate of annual seedlings reached 100% in October of that year, 30% of the seedlings died in the same year, and 20% to 69.6% of the seedlings died after overwintering. In 1991, the morbidity rate of Populus euphratica saplings in the introduction area of ​​Shapotou Desert Research Sta...

Problems solved by technology

Due to the large dosage, frequent spraying and poor effect, it has been discontinued

[0007] For many years, people have often used triadimefon (Fenxiu Ning) for prevention and treatment, and in recent years, a new drug pentaconazole (Likexiu) has been used for prevention and treatment. Although it is effective, it is sometimes not obvious, especially when the best prevention period is missed. not obvious

The main reason why Populus euphratica rust is difficult to control is that the growth of Populus euphratica is weak and susceptible to rust. Triadimefon and pentaconazole are not easily soluble in water, so the efficacy of the drugs is not fully exerted, and the control efficiency is relatively low.
