This invention relates to the field of agricultural biotechnology, and in particular to a stress-resistant, antifreeze, and preservative biofilm formulation and its preparation method. The stress-resistant, antifreeze, and preservative biofilm formulation is composed of the following raw materials in parts by weight: 13-28 parts film-forming matrix, 5.5-11.5 parts antifreeze active component, 2.51-6.05 parts stress-resistant active component, 7-14 parts crosslinking and plasticizer, 0.1-0.5 parts natural antibacterial agent, and 55-75 parts deionized water. This invention innovatively achieves a four-fold synergy of physical barrier, active stress resistance, efficient antifreeze, and natural antibacterial properties. The film-forming matrix forms a dense and breathable physical barrier, inhibiting moisture loss; the stress-resistant components construct an active stress-resistant system, enhancing the stress resistance of agricultural products; the antifreeze components achieve efficient antifreeze by inhibiting ice crystal formation and stabilizing cell membrane structure; and the natural antibacterial agent specifically inhibits postharvest pathogens such as Penicillium and Botrytis. The four components work synergistically to comprehensively solve multiple problems during the storage of agricultural products.

This invention discovers that flunilic acid can inhibit the growth of crop pathogens, thus demonstrating that flunilic acid can be used as a pesticide to control and inhibit crop pathogens, particularly those in the Ascomycota phylum (…). Ascomycota Pathogenic fungi in ); for example, it could be the genus *Gastropoda* ( Magnaporthe ), Cyclospora spp. ( Cochliobolus Fusarium ( ) Fusarium ), Botrytis ( Botrytis ) and Sclerotinia spp. ( Sclerotinia Pathogenic fungi in ).

The present application relates to the technical field of pesticide compound, especially to a kind of fungicidal composition containing boscalid and fludioxonil and application thereof;A kind of fungicidal composition containing boscalid and fludioxonil, the active ingredient contained in the fungicidal composition is boscalid and fludioxonil;The mass ratio of the boscalid and fludioxonil is 10:20~29:1;The present application discloses a kind of fungicidal composition containing boscalid and fludioxonil and application thereof, the boscalid and fludioxonil added within a certain ratio range show good synergistic effect to tomato botrytis blight, the fungicidal effect of the combination of the two is obviously higher than single agent, and the co-toxicity coefficient is above 120, the fungicidal composition prepared not only reduces its use dose and cost, but also reduces pesticide residue, reduces the harm to environment.

The invention relates to the technical field of agriculture, and particularly discloses a comprehensive pest and disease damage prevention and control method combining winter peach fruit bagging with trapping and killing technology, which comprises the following steps: in a winter peach physiological fruit dropping period, suspending insect sex pheromone trappers in an orchard, and monitoring the adult sexual period of peach fruit moths and oriental fruit moths; s2, according to the monitoring result of the step S1, all fruits are uniformly bagged before the initial emergence period of the target pest adults and after fruit setting is completed; physical bagging and various trapping and killing technologies are systematically integrated in time sequence and space, pest situation monitoring is used as a guide, the optimal window period of bagging is determined, physical isolation measures are made to play the maximum effect, a composite trapping and killing system is deployed subsequently, space differentiation configuration is conducted according to ecological habits and activity rules of different pests, and the pest trapping and killing effect is improved. Accurate coverage of the trapping and killing range and the target object is achieved.
