This invention relates to the field of agricultural chemicals, particularly to the insecticide indoxacarb, and specifically to a method for preparing the synthetic intermediate of indoxacarb. The method involves constructing an α,β-unsaturated carbonyl compound using the Knoevenagel reaction, followed by further reduction to obtain the target compound. Compared to the nucleophilic substitution reaction conditions in the original literature, this method offers milder conditions and greater solvent selectivity, making it suitable for large-scale industrial production of acyl halide derivatives. This method is not only simple and efficient, but also boasts high yield and high purity, allowing the target compound to be obtained through simple purification steps.

This utility model relates to the technical field of indoxacarb screening equipment, specifically disclosing a screening device for the production of indoxacarb technical grade, including a support mechanism and a screening mechanism. The screening mechanism is arranged on the upper inner side of the support mechanism. The support mechanism includes a support frame, with two mounting blocks symmetrically arranged at both ends of the lower part of the support frame. Telescopic rods are arranged below each of the four mounting blocks. The screening mechanism includes a screen box, with a screen plate connected to the inner side of the screen box. A top plate and a hopper are respectively connected to the upper and lower ends of the screen box. Support plates are connected to both ends of the screen box. A cam is arranged in the lower center of each of the two support plates. Multiple springs arranged in a linear array are arranged on both sides of the cam. This equipment can continuously screen indoxacarb technical grade, ensuring the continuity of the screening operation, improving the screening efficiency of indoxacarb technical grade, reducing the workload of disassembling and assembling related parts, and reducing the risk of users coming into contact with indoxacarb technical grade.

The application discloses an indoxacarb wastewater pretreatment method, belongs to the technical field of indoxacarb wastewater pretreatment, and mainly aims at 5-chloro-2-methoxycarbonyl-2-hydroxy-1-indanone, an intermediate of indoxacarb. First, the pH is adjusted to hydrolyze the indoxacarb intermediate into methanol and 5-chloro-2-methoxycarbonyl-2-hydroxy-1-indanone derivatives with carboxylate, the methanol is collected, and then the waste liquid is adjusted to be acidic. The prepared emulsion is added, liquid-liquid separation is carried out, on the basis of recycling of the methanol and the 5-chloro-2-methoxycarbonyl-2-hydroxy-1-indanone derivatives, the waste liquid meeting the national minimum emission standard is obtained, and the waste liquid is sent to a sewage treatment plant for further treatment. The indoxacarb wastewater pretreatment method has the characteristics of energy saving and consumption reduction and recycling of useful components of liquid.

Pesticidal compositions and methods of use are provided. An aqueous pesticidal suspension composition comprises indoxacarb, a dispersant, a surfactant, and water, wherein the dispersant and surfactant are present in amounts effective to maintain the indoxacarb as a stable suspension during storage. The composition may optionally include one or more formulation additives such as a thickener, preservative, antifreeze agent, or antifoaming agent. A suspension concentrate comprising higher levels of indoxacarb, dispersant, and surfactant is also provided and may be diluted prior to application. Methods of controlling pests are further disclosed, including applying an effective amount of an indoxacarb-containing composition to turfgrass or ornamental plants to control pests such as black cutworm larvae, tawny mole cricket, and Genista caterpillar. The compositions may be applied directly or as diluted spray solutions at selected application rates to provide effective pest control with acceptable plant safety.
