Embodiment 1

[0008] Embodiment 1, for the treatment of the parasitic disease of the anchor head carp, time: August 26, 2012, place: Pingqiao Reservoir, Yizhou City, Guangxi, the bottom area of ​​the reservoir is 506 mu, and the average water level is 3.5 meters high. A motor boat cruised the reservoir every day, and 3,251 fish were checked on board with nets. It was found that silver carp, grass carp, and common carp were suffering from four types of parasitism: polymorphic anchorhead, carp anchorhead, grass carp anchorhead, and four-ball anchorhead. Insect disease, at this time, the average weight of a single fish is 350 grams, and 1640 fish are sick, and the prevalence rate reaches 50.44%. On the morning of the 26th, according to the ratio of "take 50 ml of 20% deltamethrin emulsifiable concentrate per mu and mix with 30 kg of water", the whole reservoir was withdrawn, and white splashes appeared on the water surface. Three days later, on the morning of September 9th, 5,238 silver carp, ...

Embodiment 2

[0009] Embodiment two, for the prevention of the parasitic disease of Anchor chinensis, on September 6, 2012, it was implemented in a pond with an area of ​​15 mu at the bottom of the water, and the place was: Jiaotun Lingjiao Pond, Diletun, Anma Township, Yizhou City, Guangxi, The implementation concentration is: take 50 ml of 20% deltamethrin emulsifiable concentrate per mu and mix with 60 kg of water, and remove the whole pond. Afterwards, checks were made every three days for 4 consecutive checks. No occurrence of parasitic diseases of the anchorhead gnat was found, and no fish died of poisoning due to deltamethrin.

Abstract

The invention discloses application of deltamethrin in control of lernaea parasitic diseases of fishes and belongs to the technical field of control of diseases and pests in fresh water fishery. The application method is characterized by comprising the following steps: uniformly mixing 100ml of 20% deltamethrin missible oil and 30-60kg of water, spreading the mixture into the water, applying the mixture by 3-4 mu when the water level is lower than 2.5m, and applying the mixture by 2 mu when the water level is higher than 2.5m. When the water surface of a pond is green and clean, the mixture can be directly spread, and if the water is blackened and turbid, oxygenation needs to be performed by using an oxygen increasing machine, and the mixture is spread. The application method disclosed by the invention has the beneficial effects that the lernaea parasitic diseases of fishes can be prevented or controlled by utilizing deltamethrin.

Description

technical field [0001] The invention relates to the application of deltamethrin in the prevention and treatment of parasitic diseases of fish moths, and belongs to the technical field of freshwater fish industry disease and insect control. Background technique [0002] Deltamethrin is one of the pyrethroid insecticides, the molecular formula is: C 22 h 19 Br 2 NO 3 .The chemical name is: α-cyanophenoxybenzyl (1R, 3R)-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropane carboxylate, also known as dichloride , Zhuchongjing, Kai'anbao, deltamethrin has a wide insecticidal spectrum, no selectivity to natural enemies, mainly contact and stomach poisoning, and has no systemic and fumigation effects. The dosage form is 20% deltamethrin emulsifiable concentrate. Deltamethrin has a wide range of anti-insect effects in agricultural production, and it also has good effects on pests such as Lepidoptera, Homoptera, Orthoptera, and Hemiptera. Suitable for rice, cotton, fruit trees, vegetab...
