The invention discloses a pomace humic acid fully degradable water-retaining film and a production method thereof. In the process, high-activity BHA is firstly produced by solid-state fermentation technology, and then the starch industrial waste residue of a biopesticide enterprise is used to produce a fully degradable water-retaining film. The process includes: (1) crushing of BHA raw materials, solid-state fermentation under the action of complex bacteria such as fungi (Trichoderma, Aspergillus niger), yeast (Aspergillus plana, Aspergillus polydotio) and so on; (2) Starch industrial waste residue Pretreatment, film-forming processing with highly active BHA and packaging storage. The BHA-highly active fully degradable water-retaining mulch film produced by this process is widely used and low in cost, which is not only beneficial to the natural environment protection of apple production areas or processing areas, but also conducive to moisture conservation and production increase of crops in severe cold and water shortage areas in western my country.

The invention relates to a biocontrol bacterium and its application in the control of downy mildew of crops, and belongs to the technical field of crop biological control. The biocontrol fungus CGMCC No.16732 of the present invention can effectively prevent and treat downy mildew of crops, especially in the application of cucumber, soybean and grape planting, can effectively prevent and treat downy mildew of cucumber, soybean and grape; in addition, the inventor also found that The biocontrol bacterium CGMCC No.16732 of the present invention can also reduce the occurrence of crop powdery mildew, and has a growth-promoting effect on crops, and improves crop yield; moreover, the biocontrol bacterium of the present invention is compared with the chemical agents of the prior art, It is non-toxic to humans and animals, does not pollute the environment, and has no residue. In particular, it can improve the micro-ecological environment of crops and is conducive to the sustainable development of the ecological environment.

The invention relates to an acibenzolar-containing ssterilizing composition, which comprises the following active ingredients: the acibenzolar (A) and a morpholine bactericide (B). The morpholine bactericide is selected from tridemorph, fenpropimorph, and dodemorph; the mass ratio of A to B is 100:1-1:100; and the active ingredients account for 20 to 80 mass percent of the composition. The composition can be prepared into a suspension agent, a wettable powder, a water dispersible granule and other formulations. The sterilizing composition can be applied to farmlands, gardens and other places, and is used for preventing and controlling various plant diseases of crops such as grains, vegetables, flowers and the like, particularly powdery mildew and rust diseases.

The invention relates to an acibenzolar-containing sterilizing composition, which comprises the following active ingredients: the acibenzolar (A) and a pyridine bactericide (B). The pyridine bactericide is selected from fluazinam, pyrifenox, boscalid, fluopicolide, PEIP and the like; the mass ratio of A to B is 100:1-1:100; and the active ingredients account for 10 to 80 mass percent of the composition. The composition can be prepared into a suspension agent, a wettable powder, a water dispersible granule and other dosage formulations. The sterilizing composition can be applied to farmlands, gardens and other places, and is used for preventing and controlling various plant diseases of crops such as grains, vegetables, flowers and the like, particularly powdery mildew, downy mildew and epidemic diseases.

The present invention relates to the field of fungicides, more specifically, the present invention relates to a fungicide composition, a fungicide and an application method thereof, the fungicide composition comprising 4-chloro-2-(1,1-dimethylethyl) ‑5‑[[[4‑(1,1‑dimethylethyl)phenyl]methyl]thio]‑3(2H)‑pyridazinone and trifloxystrobin in a weight ratio of (2‑6 ):1. The fungicidal composition provided by the invention can effectively control downy mildew, late blight, blight, damping-off, powdery mildew, rust, anthracnose, root rot, black shank on vegetables, fruits and field crops, especially The control effect on late blight is extremely remarkable; in addition, the bactericide provided by the invention is a nanopesticide with uniform texture, can exist stably in high and low temperature environments, has strong practicability in extreme environments, and is not affected by storage conditions.
