Inventor
Pirimicarb is a selective carbamate insecticide used to control aphids on vegetable, cereal and orchard crops by inhibiting acetylcholinesterase activity but does not affect useful predators such as ladybirds that eat them. It was originally developed by Imperial Chemical Industries Ltd., now Syngenta, in 1970.
A nitrogen-doped bimetallic biochar adsorbent, and a preparation method and application thereof
This invention relates to the field of environmental functional materials technology, specifically to a method for preparing a nitrogen-doped bimetallic biochar adsorbent and its application. The method uses grape pomace as biomass raw material, which is pretreated with HCl via hydrothermal treatment, then mixed with KOH, urea, and a bimetallic source solution. The nitrogen-doped bimetallic biochar adsorbent is prepared by oxygen-limited pyrolysis carbonization. The nitrogen-doped bimetallic biochar adsorbent prepared by this invention possesses high specific surface area, hierarchical porous structure, and magnetic separation characteristics. It exhibits excellent adsorption and removal effects on the carbamate pesticides methomyl and pirimicarb in water, with maximum adsorption capacities reaching 50.97 mg·g⁻¹, respectively. ‑1 and 159.50 mg·g ‑1 It exhibits good anti-interference ability and stability in complex aquatic environments and can be used for the treatment of pesticide-polluted water bodies.

KASP primers for detecting drug resistance mutation of aphis gossypii glover and green peach aphid and application of KASP primers
The invention discloses a group of KASP primers for detecting insecticide resistance mutation of aphis gossypii glover and green peach aphid and application of the KASP primers, and relates to the technical field of agricultural biology. The KASP labeled primer group disclosed by the invention comprises a primer combination which is used for detecting resistance mutations of AgoyV62I, AgoyR81T, AgoyK264E, MperR81T, MperV101I, AgoyM918V, AgoyM918LAC, AgoyL1014FCT, MperM918LAT, MperL1014FCT, MperS431F, MperM918TTC, MperM918I, AgoyA302S, AgoyS431F and MperA302G to imidacloprid, deltamethrin, carbofuran, pirimicarb and fipronil. And detecting the drug resistance mutation of the aphis gossypii glover or green peach aphid by using one or more primer combinations. The group of KASP labeled primers is good in specificity and high in sensitivity, and can accurately detect the mutation frequency of the drug resistance of the aphis gossypii glover or green peach aphid to the insecticide.
