Abstract

The invention discloses an insecticidal composition for treating parasitic chironomidae, ephydrid larva, blood worm, and rotifer during a spirulina cultivation process. The insecticidal composition iscomposed of sodium bicarbonate, ammonium bicarbonate, calcium chloride, chlorine dioxide, sodium hyposulfite, citric acid, sodium selenite, and fulvic acid according to a mass ratio being 1: 0.1-0.2:0.1-0.15: 0.1-0.15: 0.08-0.1: 0.01-0.03: 0.01-0.03: 0.1-0.2. The insecticidal composition has no toxic and side effect, has good insecticidal effect, cannot remain in cultured objects, and thereby puts an end to food chain pollution. The insecticidal composition can rapidly and efficiently process insect pest, can increase spirulina cultivation capacity by 30%, improves a traditional cultivationmethod, and reduces the high cost of traditional cultivation.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an insecticidal culture for treating parasitic chironomus larvae, water fly larvae, red worms and rotifers in the process of cultivating spirulina. Background technique [0002] Chironomus larvae, water fly larvae, red worms, and rotifers are common parasites in the microalgae cultivation process, which are extremely harmful, especially after rains. Once they break out, they will bring huge losses to the breeding enterprises, destroy the cultivation system, and cause Unable to continue farming. [0003] At present, there are not many effective methods for controlling chironomid larvae, water fly larvae, red worms, and rotifers in domestic breeding enterprises. In actual production, in order to prevent insect pests, chemical disinfectants are often used to control algae pests. However, due to the lack of healthy farming by farmers Awareness, blindly and repeatedly...
