First, the onset of symptoms: Sunlight greenhouse eggplant Mianzhuang disease mainly harm the fruit, near-ground fruit first disease, the fruit on the primary water immersed round or near-round tan to dark brown slightly depressed lesions, the edge is not obvious, after expansion Can spread to the entire fruit, brown rot inside. A white cotton floc was produced on the surface of the lesion when wet. The diseased fruit landed or remained on the branch, and the dehydration became dry and formed a stale fruit. The lesions were round in shape, water-stained, with obvious ring patterns, and the edge was not obvious when wet. The spots produced thin vegetables with white mold. The edges of the lesions were obvious when dry and did not produce white mold. The flower rots wet and spreads to the tender stalks. The diseased brown dents and the upper branches and leaves are wilting and sagging. When wet, the flower stalks and other diseases produce white cotton.
Second, prevention and control measures
1. Select varieties to suit local conditions and select suitable resistant varieties for local planting.
2. Rotation and non-solanum crop rotations for more than 2-3 years.
3. Seed Treatment Before sowing, add 2% of 2.5% fludioxonil seed coating agent and 35% emulsified seed coating agent of refined metalaxyl, mix with 150-200ml water, and pack 4kg seeds. It can also be soaked with 68% fine amasite Mn-Zn water dispersible granules 600 times liquid for half an hour, and germination after washing.
4. Add seedling management to the seedbed soil by adding 68% refined arsenic manganese zinc 20g and 2.5% fludioxonil 10ml and mix well. Stir in the nursery bed to prevent seedling disease.
5, field management deep fall winter, apply enough organic fertilizer, increase phosphorus, potassium fertilizer. The use of sorghum film cultivation, conducive to irrigation. Pruning in time in pruning, remove diseased leaves.
6, the beginning of the drug spray prevention 66.8% propicondiamide WP wettable powder 600-800 times; 52.2% nystatin cream urea water dispersible granules 1500 times; or 70% of propyl aluminum zinc aluminum wettability Powder 500 times; 70% Prosin Zinc wettable powder 600 times; 72. 2% Proplocarb water 600 times; or 25% azoxystrobin suspension 1500 times; 53% fine A Frost manganese-zinc water dispersible granules 600 times, every 7-10 days, control 2-3 times, pay attention to protect the fruit when spraying.
Plant extracts refer to a class of substances derived from plants that have one or more biological functions. Can be separated by physical and chemical extraction of one or more effective components formed by natural products.
There are many kinds of plant extracts. At present, natural plant extracts mainly include essential oils, saponins, alkaloids, polysaccharides, polyphenols, flavonoids and so on. According to the biological activity, it can be divided into antioxidants: grape seed extract, green tea extract, pine bark extract, etc. Immune modulators: ginseng extract, gynostemma pentaphyllum extract, Ganoderma lucidum extract, etc. Improve cardiovascular function: ginkgo biloba extract, lotus seed heart extract, rhodiola extract, etc. Sedative: valerian extract, hop extract and so on.
According to their own characteristics in the market application of plant extracts can be roughly divided into six categories: coloring, seasoning, medicinal, health, dietary supplements and feed additives. Natural plant pigments refer to pigment components in roots, stems, leaves, flowers, fruits and bark of plants, such as turmeric, sappanwood, indigo, safflower, black bean and green walnut peel. Natural plant pigments are widely used in food, textiles, cosmetics, medicine, leather industry, printing and dyeing and other industries.
Plant extracts are rich in ingredients that can effectively stimulate the senses, such as sweeteners and volatile substances. Natural sweeteners, such as stevia glycoside and grosvenin, are popular new sweeteners. They are not only sweet, but also ideal substitutes for sucrose. Essential oils are concentrated volatile substances that are commonly used in the preparation of fragrances and are widely recognized in plant extracts.
Contained in the plant extracts of saponins, alkaloids, polyphenols, flavonoids and other ingredients are widely study has many biological activities, such as antioxidant, antibacterial, anti-inflammatory, improve animal production performance, antivirus, enhance immunity, etc., for human and animal health has the effect of nots allow to ignore, and the development of its pharmacology and health care function has become the main trend of plant extracts.In addition, as a dietary supplement, it is one of the main applications of various plant extracts. Such as oligosaccharides (oligosaccharides, oligosaccharides, oligosaccharides, galactose, etc.) dietary fiber, soybean protein, dietary fiber, wheat albumin, L-arabinose, sugar alcohol (xylitol, malt heavy sugar alcohol, sorbitol, etc.) and other natural plant food additives have been widely used in the food health care market. Many plant functional ingredients with anti-inflammatory, antioxidant and bacteriostatic properties are also commonly used as substitute anti-bacterial products. The application of green feed additives in livestock and poultry production has been vigorously developed, such as green tea polyphenols extract, pine bark procyanidins extract and polyanthocyanidins extract.
Due to the changes in lifestyle, working mode and consumption mode, more consumers are pursuing the life concept of "big health". The so-called "big health" refers to a concept of whole-process, comprehensive and total factor care for people's life around the basic necessities of life, life, old age, illness and death. It not only pursues individual physical and physical health, but also pursues mental, spiritual, social, environmental and family health. In the era of "great health", natural plant-based health products are the core and the key material basis.
With increasing attention to the food and drug safety, from natural plant in the development and utilization of the active ingredient is becoming more and more attention, a large number of food safety, have certain curative effect function of plant extracts have been used as raw materials in a variety of ways into functional food nutrition and health food has entered people's lives, and will play a more and more important role.
And more and more new research new discovery, predicts that the plant extract industry chain will have more members to join, there will be more business opportunities. The future domestic plant extract market will stride forward gradually to mature period!
