Embodiment 1

[0113] Take neem oil 19%, water 80%, Tween 60 0.7%, Span 60 0.3%; heat the water to 50-60°C2, add Tuwen 60 and Span 60, stir until the added substances are completely dissolved, And add neem oil under stirring state, continue stirring solution to whitish, input high-pressure homogenizer after homogenizing 1 time under the pressure of 300Mpa, add the citric acid 0.1% of above-mentioned total amount, potassium sorbate 0.09%, EDTA. .1%, 0.005% azadirachtin or 0.008% natural pyrethrins were mixed and then homogenized 3 times to complete the preparation of neem oil emulsified water emulsion.

Embodiment 2

[0115] Take neem oil 1%, water 94%, Tween 60 3%, Span 60 2%; heat water to 50-60°C, add soil temperature 60, Span 60, stir until the added substances are completely dissolved, and Add neem oil under stirring state, continue to stir solution to whitish, input high-pressure homogenizer under the pressure of 600Mpa homogenization 1 time, add the citric acid 0.01% of above-mentioned total amount, potassium sorbate 0.01%, EDTA0. 01%, azadirachtin 0.001% or natural pyrethrin 0.005% and then homogenized three times to complete the preparation of neem oil emulsified water emulsion.

Embodiment 3

[0117] Get neem oil 49%, water 50%, Tween 80 0.65%, Span 80 0.35%, carry out by the step of embodiment 1, add the citric acid 0.18% of above-mentioned total amount, potassium sorbate 0.08%, EDTA0.1 %, azadirachtin 0.05% or natural pyrethrins 0.01%; the following steps are still the same as in Example 1.

Abstract

The neem oil preparation consists of neem oil, water, Tween-60 or Tween-80, Span-60 or Span-80, citric acid, potassium sorbate, EDTA, and nimbin or natural avermectin. The neem oil preparation has high effect of preventing and treating parasitic disease of aquatic animals and no resistance, owing to the functional mechanism including lowering intestinal tract activity, inhibiting ecdysis, inhibiting mating and oviposition, refusing feed, inhibiting egg development, etc. In addition, the present invention has low cost.

Description

technical field [0001] The invention relates to a preparation for preventing and controlling parasites in aquaculture by using neem oil and a preparation method thereof. Background technique [0002] China is the country with the largest aquaculture. Every year, due to the parasites in the culture such as: trichomonas, small melon worms, ciliates, sporozoites, oblique tube worms, ring worms and other hazards, the aquaculture industry has caused huge losses. In the process of aquaculture parasites, a series of chemical preparations such as trichlorfon, potassium permanganate, and malachite green are widely used, although this series of chemical preparations play an important role in the process of preventing and controlling aquaculture parasites. It plays an important role, but its natural degradation in water is slow, and the drug resistance of target insects continues to increase, resulting in a vicious circle of increasing dosage. The use of chemical drugs also makes the dru...
