New techniques for prevention and treatment of kiwi canker
1. Disease description
It damages new shoots, branches, leaves and flower buds, but generally does not damage roots and fruits. After the plant is injured, the disease begins in mid- to late-month. Longitudinal cracks appear on the branches and vines, and dark green water-soaked mucus oozes out. Under high humidity conditions, white bacterial pus is secreted in the cracks, and finally the tissue at the gummy area sinks and turns black. There are rust-like canker spots, and the upper branches of the diseased area are cracked, shrunken and dead. After the leaves are damaged, dark brown lesions appear, and the outer edges of the lesions turn yellow. Severely diseased leaves curl inward, become scorched, and fall off easily. After the flower buds are damaged, they turn brown and die before blooming, the flower organs are damaged, and the corolla turns brown and becomes water rot.
2. Product Description
"Kai Fu Ling" traditional Chinese medicine preparation, the original solution is not harmful to branches, and the solution above is not harmful to young flowers, fruits, and leaves. It can sterilize, repair wounds, and promote healing. .
"Liang Guo'an" traditional Chinese medicine preparation has no phytotoxicity on young flowers, fruits, and leaves at a dosage of 100% or more, and has bactericidal and rejuvenating effects.
"Qingkulik" traditional Chinese medicine preparation has dual functions of sterilizing roots and promoting rooting. It is harmless when used in high concentrations.
"Wo Feng Su" is nutritionally comprehensive and contains amino acids, humic acid, polysaccharides, trace elements zinc, boron, etc.
3. Prevention and treatment plan
Treatment plan:
) Application: For wounds with small and few bleeding spots, scrape off the cortex of the diseased area, use a knife to cut lengthwise to the xylem, and use Apply the original solution of "Ling" to the area larger than the area of the lesion. Apply it 3 times, once on the first, third and third days. If the disease is serious and there is still water stains, apply it again on the next day. If the wounds are large or numerous, cut off the diseased branches, and then use the original solution of "Kai Fu Ling" to smear the cutting edges.
) High-concentration rinsing: For the plants with ulcers, use 3-fold solution of "Kaifuling" and rinsing-drying once, with intervals of a few days.
3) Root irrigation: For diseased plants with severe ulcers, many spots, and in the growth period during the rainy season, root irrigation methods should be adopted on the basis of smearing and rinsing. Specifically, in spring, use "Green Withered Stand" Mix 3 times of solution + 3 times of Jiejibao + 3 pounds of organic silicon with water and irrigate the roots once, with an interval of - days, until the capillary root zone is fully irrigated. A bottle of trees less than 3 years old - a bottle of trees older than 3 years - a bottle of 3 trees for old and disadvantaged trees.
) Spray: Use Liangguoan 3 times, Wofengsu times + silicone to spray the leaves several times, with intervals of several days each time.
Prevention plan:
Garden clearing plan during the spring budding period
Plan: Use cyclosporin-double liquid + organic silicone whole garden spray.
Purpose: To sterilize bacterial sources in the early stages of active activity, repair wounds before sap flows, nourish tree trunks, and reduce or avoid the occurrence of pathogens.
Root irrigation plan (root growth period)
Plan: In spring, use "Qingkulik" twice the solution + Genji Bao + organic silicon mixed with 3 pounds of water to irrigate the roots once, with an interval of - days, to irrigate thoroughly The capillary root zone shall prevail. A bottle of trees less than 3 years old - a bottle of trees older than 3 years - a bottle of 3 trees for old and disadvantaged trees.
Purpose: Roots absorb and sterilize (including bacteria that cause root rot and root cancer), promote rooting, improve root absorption capacity, and directly provide nutrients for crops to achieve rejuvenation effects.
Leaf-expanding stage
Plan: 3 times liquid of Liangguoan, 3 times liquid of Wofengsu + spray of silicone.
Purpose: Use Liangguoan spray during the leaf expansion period to promote leaf expansion, the leaves will turn green quickly, photosynthesis will be enhanced, and more organic matter will be produced.
Blooming period
Plan: Spray Liangguoan liquid + organic silicon all over. Those engaged in green organic production can increase the concentration of Liangguoan to 100%.
Purpose: To protect flowers and kill sources of eubacteria.
Fruit growth period
Plan: Liangguoan 3 times, Wofengsu times + silicone spray more than once, with an interval of about - days between each time.
Purpose: Continuously conduct sterilization and nutrition through spray to rejuvenate the tree body, promote photosynthesis, produce more organic matter, and also nourish the tree. It has broad-spectrum bactericidal effect on other leaf diseases.
Plan for garden cleaning after fruit picking
Plan: Use Kuefuling double liquid + Wofeng Sudou + organic silicone whole garden spray.
Purpose: to sterilize and repair fruit marks and wounds, to prevent pathogens from invading the plant, to reduce the residual amount of pathogens in the plant, and to prevent damage by pathogens in the coming year
Garden clearing plan for fallen leaves/3 hours
Plan: use Kefuling-doubled liquid + organic silicone garden spray.
Purpose: To sterilize and repair leaf marks and wounds, prevent germs from invading the plant, reduce the amount of germs remaining on the plant, and prevent the damage of germs in the coming year
Apply the saw cuts
Plan: For physical pruning, pathology The cut marks formed by pruning should be smeared once with Kufuling liquid + silicone.
Purpose: Repair wounds caused by agricultural operations, promote healing, stop bleeding, and reduce infection
4. Expected effect standard:
. Treatment expected effect standard
) Stop bleeding and heal Effect: After applying it for half a month, it can usually be achieved. The ulcers and lesions on the affected area will disappear like water stains and look dry. After a month, new skin will grow.
) Tree preservation effect of wounded trees: During the high-incidence period of canker disease, if the water flow is serious, especially the red water flow, even if "Kai Fu Ling" is used to achieve the effect of stopping the flow, the tree will be damaged due to excessive nutrient loss. Unable to sprout, regenerate, and create nutrients to support the root system, individual branches and tree bodies will undoubtedly die. For some plants, too much water flows on a certain trunk branch in early spring, which may also cause the entire tree to die (the pressure difference between the injured part and the root is large, causing all the sap to flow out). As long as the tree body develops its leaves and grows normally after the injury period, nutrients are created and the tree can no longer die on the basis of nutritional rejuvenation.
.Standard for expected prevention effect
) Disease prevention effect: disease reduction or rare occurrence: the incidence rate in the first year of use can be reduced by more than 3% compared with previous years, specifically related to the strength of the tree, the incidence of disease in previous years, etc. Factors are related. If Chinese medicine is used continuously, the effect will be cumulative. According to Zhang Qingming's 3-year statistics from the Zhouzhi Experimental Station in Shaanxi: the incidence rate in parks that use chemical agents reaches 3, while those that use traditional Chinese medicine reach . The effect is remarkable.
) Rejuvenation effect: spray the fruits every year
Leaves: large, thick, bright, green, soft, and stretched
Current-year branches: fresh, thick, short internodes, Hairless and long
Trunk: smooth, clean bark, green color
Fruits: less deformed fruits, high sugar content, long shelf life
Leaf buds and flower buds in the following spring: the tree turns green quickly and has full buds. Strong, uniform flowers with clean color and no burns on petal edges
Root system: many capillary roots, long
Strong stress resistance: enhanced disease resistance and frost resistance.
3. In terms of safety and environmental protection: no drug resistance, no residue, pure traditional Chinese medicine ingredients can be used continuously, and it does not affect green organic standards.
