The Mechanism of action of Chitosan oligosaccharide MECHANISM  The mechanism is that plant can produce chitinase by absorbing Chitosan oligosaccharide to interact with pathogenic bacteria, inhibit the growth of pathogenic bacteria, make susceptible plants produce systemic resistance, promote plant synthesis of phytoprotegerin, stimulate the synthesis and accumulation of plant lignin, and at the same time promote the activity of plant disease-resistant enzymes.With the systemic resistance of plants, the vascular bundles of stem base had no lesion or lessened obviously, the root system was developed, the plant was strong, the fresh weight of individual plant was increased, and the disease resistance was improved.   ECO-FRIENDLY,WITHOUT ANY RESIDUES Chitosan oligosaccharide are different from traditional pesticides .  It does not directly affect harmful organisms, but stimulates the immune responses of plants themselves(including sterss resistance)to play an i...

There are more than 30 known grape diseases. Among them, sour rot, anthrax and powdery mildew are the most common diseases. If we know more about grape diseases, we can improve grape growing environment, promote grape yield and improve economic benefits. Grape Sour Rot Sour rot  is usually caused by the mixture of acetic acid bacteria, yeasts, fungi, Drosophila larvae and other microorganisms. It is a serious disease that can reduce grape yield by 30%-80%. Symptom  There are rotten grapes, if it is bagged grapes, under the bags there is a dark moist, while there are vinegar flies around the rotten ears, emitting acetic acid taste. White maggots can be seen in the rotten fruit. As the rotten juice flows out, the place where the juice flows will rot. Site of occurrence ：Fruit Occurrence stage ：After grape sealing→When grapes are colored Best prevention time ：Staining to Maturity Grape Powdery Mildew It is a common disease of many ...

What's Triacontanol ? Triacontanol is a plant growth regulator for many plants.It can be used as photosynthesis enhancer.As we know,photosynthesis is the most important life activities,most of the plants energy come from photosythesis. When applied on plants, it can significantly increases the amount of chlorophyll in leaves, thereby improving the rate of photosynthesis.It can also increase the rate of cell growth,nitrogen fixation,enzymes activities,free aminoacids, reducing sugars,and soluble protein of plants. After using triacontanol,it increases crop's resistance ability and reduce the use of triditional pesticide.Finally help crops have a good promote on yields and quality. Suitable for various of vegetables,fruits and other crops... Advangages  of Triacontanol Stimulate formation of bud,flowers and plant branching. Increase photosynthesis and plant metabolism.  Stimulate cell growth,build healthy root system, thicken plant’s foliage and flowers. Make ...

Target Crops Tomato vegetables, peppers,  carrots and lots of other vegetable crops. Tomato vegetables are moderately prone to root knot nematodes. Where to find  All over the world, in warm temperate climates Brief info Root knot nematodes are small eelworms living in soil and be plant parasites once they use tomato roots as their nurseries. Usually nematodes enter tomato roots through plant’s small injuries.With the increase of number of nematodes, healthy plant’s roots are destroyed, and twisty galls to take their place. Bad influence Plants grow progressively, in erratic spurts, and they’re dwarfed wide. In situation you uncover a troubled tomato, numerous swellings and galls are apparent within the roots. Because root knot nematodes don’t move for long distance within the soil without farmer’s help, neighboring plants might be infected while individuals inside the finish within the row stay healthy. How to prevent Tomato vegetables and peppers are m...

If you grow grapes,you may reaching to see a white powdery substance on the grape leaves.It’s the grape powdery mildew. Especally in main grapevine growing area such as Americas,Europe and Australia. The disease seems as a whitish-gray powdery coating on the leaves or fruit caused by plant mycelium and conidia on the surface of the plant. On leaves, initial symptoms seem as chlorotic spots on the leaf surface that presently become whitish lesions. While this can be common,it’s a disease which will injury your grape plants and your crop if left untreated. Manual management Disease development is powerfully favored by high humidness and cloudy weather, additionally to comparatively heat temperatures. Manual management of powdery mildew helps prevent the disease from overwintering in bark crevices and also the spread of current infections. powdery mildew infects leaves, shoots, bark and developing fruit on grapevines, releasing spores in spring throughout heat, wet cond...

Plant disease is the main enemy of agricultural production. According to the Food and Agriculture Organization of the United Nations (FAO), the average annual loss of production due to plant diseases is 10% to 15%. At present, the main means of controlling plant diseases is chemical fungicides. However, due to potential human health hazards, environmental pollution, non-target organisms, and development of plant pathogen resistance, the development of chemical fungicide has been limited. Biological fungicide are attracting more and more people’s attention and interest. What’s Biofungicides? Bio-sourced fungicides refer to the direct use of biologically active substances produced by biological organisms or biological metabolic processes or substances extracted from organisms as a disease prevention and treatment. The concept of biological pesticides is vague and can be considered equivalent to biologically derived fungicides. According to s...
