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.

The invention discloses an enterobacter cancerogenic EcCB2 strain and an application thereof. According to the present invention, the enterobacter cancerogenus EcCB2 strain is separated from lasioderma serricorne, and is preserved in Guangdong Province Microbial Culture Collection Center on May 31, 2024, and the preservation number is GDMCC No: 64709; the EcCB2 strain not only can effectively kill vegetable pests such as beet armyworms, spodoptera litura, prodenia litura, plutella xylostella and cabbage caterpillars which are mainly harmful to brassicaceous vegetables, but also can remarkably inhibit the growth of plant pathogenic fungi such as fusarium oxysporum, sclerotinia sclerotiorum, colletotrichum hijinensis and alternaria solani; the compound can be used for preventing and treating plant diseases caused by plant pathogenic fungi and cruciferous vegetable insect pests.

The invention discloses a method for interplanting Yunnan wood and buckwheat, which belongs to the technical field of agriculture and comprises the following steps: S1, selecting a planting field: selecting a sandy loam field with the altitude of 2700-3100 meters and the pH value of the soil not higher than 7; s2, soil preparation: applying 1500-2000 kg of decomposed organic fertilizer per mu in combination with deep ploughing, and drying the land in the sun after ploughing; shallow ploughing is carried out again before the saussurea costus is sown, 75 mL of 50% phoxim emulsifiable concentrate is mixed with 2-3 kg of fine soil to be applied per mu before shallow ploughing, 30 kg of compound fertilizer with the ratio of N to P to K being 15 to 15 to 15 is applied per mu, and then ditching and ridging are carried out; s3, planting the saussurea lappa in a seed dibbling mode from April to May in a punching and mulching film covering mode, the planting space is 25 * 25cm, and 1-2 saussurea lappa seeds are dibbled in each hole; s4, sowing tartary buckwheat in the ditches in July of the next year in the current year of sowing the Yunnan wood. According to the method, by means of interplanting of the caesalpinia tonkinensis and the buckwheat, the crop yield can be increased, the morbidity of root rot of the caesalpinia tonkinensis is reduced, and the incidence rate of aphids, cercididae, short-amount locusts and cutworms is reduced.
