Abstract
The invention discloses a special killing drug of Enterocytozoon hepatopenaei in prawns and a preparation method and application of the special killing drug. The special killing drug of Enterocytozoonhepatopenaei in prawns includes the following components: in percents by weight, 30-60% of albendazole, 10-30% of bile acid, 5-15% of Phyllanthus urinaria powder, 10-20% of artemisia apiacea powder and 5-15% of vitamin C. Application of the special killing drug comprises the steps: in percent by weight, taking the drug, mixing 1-2% of the drug with feed evenly, then spraying a diluted adhesive, performing drying for use, and performing application continuously for 2 weeks or above, wherein the drug can also be used as a feed additive, and be added into the feed at a ratio of 0.5-1% by weight.The combination and matching of the drug are reasonable and scientific, and hepatopancreas of the prawns can be protected through the synergy of the pesticide effects of the components, so that Enterocytozoon hepatopenaei in the prawns is killed, growth of the prawns is accelerated, and the immunity of the prawns is improved.
