Method for simultaneously preventing pink bollworm and American bollworm, the method including at least: a step in which cotton seedlings are planted in a field 21-41 days after the date of occurrence of the adult stage of the pink bollworm in the case of the first generation, and 1-29 days after the date of occurrence of the adult stage in the case of second and subsequent generations; and a step in which an extended-release pheromone preparation including at least Z,Z/Z,E-7,11-hexadecadienyl acetate, which is a sexual pheromone substance for pink bollworm, and Z-11-hexadecenal, which is a sexual pheromone substance for American bollworm, is implanted in the field 2-15 days before the expected date of occurrence of the adult stage of the next generation of pink bollworm, the expected date derived from the effective integrated temperature, and the sexual pheromone substances in the extended-release pheromone preparation are released in the field.

A biocide blend can be used in an oil or gas operation. The biocide blend can include a first biocide of a formaldehyde-releasing biocide and a second biocide of a quaternary ammonium compound. The formaldehyde-releasing biocide can release formaldehyde after introduction into a wellbore. The first and second biocide can possess at least one property that is the same. The first biocide and/or the second biocide can maintain biocidal activity for extended periods of time in high salinity wellbore fluids, be thermally stable, and less expensive than other biocides.

Disclosed is a method for preparing an attapulgite-based pH-responsive antibacterial material, including: directly spraying a natural aldehyde-based antibacterial agent onto an attapulgite powder under stirring, and constantly stirring the attapulgite powder for 20-30 min; grinding the attapulgite powder in a ball mill for 30-60 min to obtain a ground attapulgite powder; placing the ground attapulgite powder in a stirred tank, and spraying a chitosan-citric acid aqueous solution onto the ground attapulgite powder; after spraying, constantly stirring the ground attapulgite powder for 30-120 min; and finally drying the ground attapulgite powder to obtain a dried attapulgite powder, sieving the dried attapulgite powder to obtain a sieved attapulgite powder, and packaging the sieved attapulgite powder to obtain the antibacterial material.
