This application discloses a Penicillium strain with stress resistance, growth promotion, and insecticidal functions, and its applications. The preservation number of this Penicillium strain is CGMCC No. 42545. This Penicillium strain naturally integrates four functions: salt tolerance, drought tolerance, plant growth promotion, and insecticidal activity against lepidopteran pests. It can grow normally in a 15% NaCl concentration medium, significantly improving plant survival rate under drought stress. Simultaneously, it promotes growth indicators such as root length and root fresh weight in crops like peas. It exhibits highly effective lethal activity against young larvae of lepidopteran pests such as diamondback moth and beet armyworm, and has high safety against non-target organisms. This Penicillium strain can be prepared into solid or liquid inoculants, showing promising application prospects in stress resistance, growth promotion, and pest control for crops grown in saline-alkali / arid areas. It realizes an integrated solution of "stress adaptation - crop growth promotion - pest control," replacing the combined use of multiple single-function agents and reducing agricultural production costs.

This invention provides a near-infrared responsive hydrogel loaded with a eutectic solvent-based pesticide and its preparation method. To address the problems of poor solubility and low utilization efficiency, flonicamid is first prepared as a eutectic solvent with citric acid, urea, or lactic acid, exhibiting stronger insecticidal activity against diamondback moth while significantly improving water solubility compared to flonicamid. Furthermore, 5,10,15,20-tetra(4-cinnamamidophenyl)porphyrin is synthesized as a photothermal conversion center and copolymerized with the thermosensitive monomer N-isopropylacrylamide via free radical polymerization to form a three-dimensional hydrogel network, achieving effective loading of the eutectic solvent-based pesticide and adhesion to plant leaves. The preparation process requires no special equipment and is effective and reliable. Under near-infrared light irradiation, the photothermal conversion center generates localized heat, inducing a hydrophilic-hydrophobic transition in the hydrogel, leading to its shrinkage and controlled pesticide release. This invention provides a pathway for developing efficient and ideal intelligent pesticide delivery platforms for sustainable agriculture.
