Problems solved by technology

However, the existing boric acid cockicides have a short duration of insecticidal effect after being put in, and the process is complicated, requiring special equipment and high cost
[0006] At present, there is no cockroach-killing agent compounded by insecticidal fungi and boric acid in the market and in the literature. The reason is: the compatibility between boric acid and insecticidal fungi is poor, and boric acid will inhibit the growth of insecticidal fungi, resulting in the compounding of boric acid and insecticidal fungi. After that, the survival time of insecticidal fungi is short, which affects the insecticidal activity of the prepared agent

Embodiment 1

[0049] Coated boric acid, its preparation method is: mix xanthan gum with deionized water into a 1% solution, then add boric acid to make the boric acid in the solution 20%, mix evenly and spray dry to obtain the coating The boric acid content in the coated boric acid was measured in accordance with "GB / T12684-2006 Industrial Boride Analysis Method", and the mass content of boric acid in the coated boric acid was 95.2%.

Embodiment 2

[0051] Mix xanthan gum with deionized water into a solution with a mass fraction of 5%, then add boric acid to make the mass fraction of boric acid in the solution 20%, mix evenly and spray dry to obtain coated boric acid, and detect the prepared coating The method for detecting the content of boric acid in boric acid is the same as in Example 1, and the mass content of boric acid in the prepared coated boric acid is 80.0%.

Embodiment 3

[0053] Mix gelatin with deionized water to make a solution with a mass fraction of 3%, then add boric acid to make the mass fraction of boric acid in the solution 20%, mix evenly and spray-dry to obtain coated boric acid. Test the prepared coated boric acid The detection method of boric acid content is the same as that in Example 1, and the mass content of boric acid in the prepared coated boric acid is 87.0%.

Abstract

The invention belongs to the technical field of biocides, insect repellents or attractants containing boron compounds, and particularly relates to film-coated boric acid. The film-coated boric acid isprepared by coating a film-coating material to boric acid. The film-coated boric acid has good compatibility with insecticidal fungi.

Description

Technical field [0001] The invention belongs to the technical field of biocides, pest repellents or attractants of boron-containing compounds, and specifically relates to a film-coated boric acid and its application in preparing a fungus and cockroach killer. Background technique [0002] The scientific name of cockroach is cockroach, also known as tea worm, fragrant lady, stone ginger, negative plate, talc, oil worm, cap, stove mackerel, red bull cattle, Helangzi, Jiayou, etc. ("Overview of research on cockroaches and their control in China", Sun Jun et al., Beijing 21st Asia-Pacific Management Association Annual Conference Paper Collection, pages 239-246, public date December 31, 2009), is a very harmful sanitary pest, it carries a variety of pathogens, and Contaminating food, utensils, and biting objects by excretion poses a great threat to human health and normal life and study ("Cockroach Control Progress", Sun Chenxi, Medical Animal Control, 2003 Vol. 19 No. 1, No. 300- 30...
