What s wrong with the yellowing of the branches of Sunshine Rose grapes?

Sunshine Rose. Why is there a large area of yellowing?

1. If the leaves of the whole garden are yellowed quickly, it is likely to be a pesticide damage. (Because of the lack of nutrients or diseases, it is unlikely that the whole garden will break out soon).

2. If it is sporadic and some plant leaves are yellowing and there is a process, it may be a nutrient deficiency, root disease or leaf disease.

3. If the yellowed leaves have green veins, but the veins are yellow, it may be iron deficiency or magnesium deficiency. We can continue to subdivide that if the old leaves are yellow and the new leaves are not yellow, they can be identified as magnesium deficiency, and if the old leaves are not yellow and the new leaves are yellow, they can be identified as iron deficiency.

4. If the veins of the yellowed leaves are yellow and the veins are green, then it can be identified as a viral disease.

5. If there are yellow spots on the yellowed leaves, and the yellow spots are slowly necrosis, it can be identified as a fungal disease of the leaves.

6. If the yellowed leaves first dry up from the edge of the leaves, but the leaf veins and leaf veins are still normal, then it can be identified as root damage or fertilizer damage.

Second, the specific interpretation of the yellowing of grape leaves.

1. Yellowing of leaves caused by pesticide damage.

The yellowing of the leaves caused by the pesticide damage is generally manifested in 3-5 days after the spraying, and the location of the pesticide damage is not the old leaves, nor the new leaves, but the middle leaves, and it is the yellowing of the whole garden.

1) Mancozeb.

Pesticide damage: pesticide damage caused by inferior mancozeb; The use of low-quality mancozeb leads to yellowing of leaves.

Generally, it is not recommended to use non-complexed mancozeb at the young leaf stage and young fruit stage, and it is recommended to use high-quality fully complexed mancozeb, mancozeb or propylene zinc. (2) Symptoms of pesticide damage caused by organophosphate agents: the leaves are more tender in the young fruit stage of grapes, and in high temperature weather.

The use of organophosphate agents can also cause burns to the leaves and yellowing.

3) The pesticide damage caused by the fog machine: the spraying of the fog machine saves water and trouble, but if it is not operated properly, it will lead to uneven local medication and drug damage symptoms.

2. Yellowing of leaves caused by nutrient deficiency.

1) Magnesium deficiency yellowing: magnesium deficiency causes yellowing, which does not occur in the whole garden, and the manifestations are: the old leaves are yellow, and the new leaves are normal; And only the veins of the leaves are yellow, and the veins are still green.

2) Iron deficiency yellowing: iron deficiency causes yellowing, which does not occur in the whole garden, and the manifestations are: new leaves are yellow, and old leaves are normal; And only the veins of the leaves are yellow, and the veins are still green.

3. Yellowing of leaves caused by viral diseases.

The yellowing of leaves caused by viral diseases occurs sporadically, mainly manifested in the yellowing of leaf veins, which are still green between leaf veins.

4. Yellowing of leaves caused by fungal diseases.

Leaf disease causes yellowing, which only forms small yellow spots on the leaves, and then the lesions dry up and die.

5. Yellowing of leaves caused by fertilizer damage and root damage.

The yellowing of the leaves caused by this cause first appears as a yellowing of the edges of the leaves, followed by gradual drying, rather than starting from the inside of the leaves.

The above are several causes of yellowing of grape leaves, in production, find the cause of the disease, and deal with it accordingly.

Is there a lack of water? Without moisture, it will also wilt.

Nutrition should also keep up, and proper fertilization can be done. Plenty of water and sunlight are easier to feed.

Why does Sunshine Rose have a large area of yellowing? is typical of magnesium deficiency. If the leaves are deficient in magnesium prematurely, it will not only directly affect the yellowing of the leaves, but also the photosynthesis ability of the leaves will plummet, and the ability of the leaves to produce nutrients will be insufficient, and it will also affect the transportation of sugar to flowers and fruits.

If magnesium supplementation is insufficient, there will also be a phenomenon of magnesium deficiency yellowing in the leaves around the ear. Shidezan magnesium-containing macro-element water-soluble fertilizer can be applied, and the leaves can maintain green leaves during the period of grape fruit expansion and veraison, and continue to efficiently provide photosynthesis products into the fruit, which significantly increases the single fruit weight, beautiful ear and full fruit.

Summary. The redness of the sunshine rose grape fruit shaft is caused by the presence of mold.

The redness of the sunshine rose grape fruit shaft is caused by the presence of mold.

At the beginning of the disease, brown water-soaked spots are produced on the branched cobs of young spikes, and after rapid expansion, the cobs become brown and necrotic, and the fruits lose water and wilt or fall off. Before and after grape flowering, spray 600-800 times of 75% chlorothalonil wettable powder or 400-600 times of 70% mancozeb wettable powder, 500 times of 40% grammedanolan wettable powder, and 1500 times of 50% promethane wettable powder. At the beginning of the disease or 4-5 days after flowering, spraying 500 times the solution can strengthen the lignification of the cob and reduce the fruit drop.

Hello dear, it's a pleasure to answer for you what's going on with the redness of the sunshine rose grape stalks? The redness of the fruit stalk may be due to the following reasons:1

Excessive watering: Sunshine Rose grapes need plenty of water, but if overwatered, the fruit and branches are prone to rot, resulting in red stems. 2.

Plant malnutrition: The redness of the stems of the Sunshine Rose grapes may be due to the lack of nutrients in the plants, resulting in poor fruit development and red stalks. 3.

Pest and disease attack: The redness of the fruit stalk may be due to the attack of pests and diseases, such as grape aphid, grape leaf borer, etc., resulting in damage to the fruit and fruit branches, and the fruit stalk turning red. 4.

Climatic factors: The redness of the fruit stalk of the Sunshine Rose grape may be due to climatic factors, such as high temperature, drought, etc., which lead to poor fruit development and red stalks. For the redness of the fruit stalk, the following measures can be taken:

1.Control the amount of watering and keep the soil moist but not over-moist. 2.

When planting Sunshine Rose grapes, pay attention to fertilization and management to ensure adequate nutrition for the plants. 3.Regularly inspect the plants for pests and diseases, and take timely measures to prevent and control problems if they are found.

4.According to the climatic conditions and the development of the fruit, timely measures should be taken to adjust the light, temperature and other factors to ensure the healthy development of the fruit. I hope this service can help you, thank you for your consultation, and I wish you all the best!

Sunshine grapes are seriously yellowed, is a lack of zinc, to timely foliar spray zinc fertilizer, and at the same time with the powder potassium dihydrogen phosphate, potassium dihydrogen phosphate is the most selected foliar fertilizer on the market, it is recommended to use powder potassium dihydrogen phosphate, but the choice of powder potassium dihydrogen phosphate also has certain skills. The market is divided into powder and crystal, to choose powder, better soluble than crystal, high absorption and utilization rate. Choose hormone-free potassium dihydrogen phosphate, which will not cause hormonal growth to the crop.

In the year of planting of Sunshine Rose grapes, the application of available nitrogen fertilizer was mainly used to promote the rapid growth of the plant. Before germination, fast-acting nitrogen fertilizer is applied to promote neat and robust germination. At the early flowering stage, phosphorus and potassium fertilizers were applied to promote the growth of new shoots and increase the fruit setting rate.

During the fruit expansion stage, potassium fertilizer was used as the main fertilizer to promote fruit development.

2kg of water-soluble compound fertilizer with nitrogen, phosphorus and potassium content of 15:15:15 can be applied per mu, which can be used at the same time as water-soluble fertilizer and water fertilizer, once a week, during which the soil is kept moist.

At the same time, during the grape growing season, according to the grape's nutrient requirements, topdressing can be carried out outside the roots. If the grapes are sprayed with foliar fertilizer after fruit set, they can continue to supplement nutrients, and Yanwo potassium dihydrogen phosphate can be used to supplement the phosphorus and potassium needs of the tree. 7-10 days after fruit harvest, it helps the plant to regulate growth, promote nutrient absorption, and restore the tree's vigor as soon as possible.

<> the branches of Sunshine Rose grapes are yellow, and the branches gradually turn yellow from the base, that is, there is a problem with the root system of Sunshine Rose grapes, and the nutrient absorption of the roots is not good, so it is necessary to look at the soil.

Sunny Rose Grape Fertilizer and Water Management.

In the year of planting, the application of available nitrogen fertilizer was mainly used to promote the rapid growth of plants. Before germination, apply Pica nitrogen fertilizer to promote neat and robust germination. At the early flowering stage, phosphorus and potassium fertilizers were applied to promote the growth of new shoots and increase the fruit setting rate.

During the fruit expansion stage, potassium fertilizer was used as the main fertilizer to promote fruit development.

Apply basal fertilizer in mid-October, early application of basal fertilizer can make it play an early role, promote new roots, in order to facilitate the tree to be strong in the coming year, apply rotting sheep manure with microbial agents, the more bacteria can enhance the activity of the soil, decompose the nutrients in the soil, for grapes to absorb, you can choose to feast on the microbial agent, containing 2 billion bacteria, is 5-6 times that on the market.

Foliar top dressing should be carried out according to the growth status during the growing season, generally from late April to before fruit picking, spray 1 potassium dihydrogen phosphate, spray 1 borax before flowering, or Yanwo boron fertilizer, completely soluble in water, safer. Irrigation is carried out in combination with fertilization. At germination, combined with fertilization and irrigation, irrigation once; Watering once before flowering, control the water during flowering, and the last irrigation before flowering should be carried out one week before flowering; Combined with fertilization and irrigation at the fruit expansion stage, irrigation once was carried out; Water control during fruit ripening, watering once before freezing in November.

At other times, water at the right time according to moisture.

Hello dear, the yellow leaves and yellow fruits of the Sunshine Rose grape may be due to the following reasons:1Water shortage:

If the soil is too dry, the plants will not be able to absorb enough water and nutrients, resulting in yellow leaves and yellow fruits. It is recommended to increase the frequency and amount of watering to ensure that the soil remains moist. 2.

Lack of fertilizer: If there are not enough nutrients in the soil, plants will not be able to grow and develop properly, which will also lead to yellow leaves and yellow fruits. It is advisable to fertilize the plants, using an appropriate amount of organic fertilizer or compound fertilizer.

3.Pests and diseases: Certain pests and diseases can also cause yellow leaves and yellow fruits in plants.

It is advisable to check whether the plants are attacked by pests and diseases, and take corresponding control measures. 4.Climate Issues:

If the ambient temperature is too high or too low, it can also affect the growth and development of the plant, resulting in yellow leaves and yellow fruits. It is recommended to plant and manage plants at the right temperature. To sum up, corresponding measures should be taken according to the specific situation to empty the sunshine rose grapes to solve the problem of eggplant deficiency yellow leaves and yellow fruits.

The yellow leaves of Sunshine Wei grapes are caused by a variety of reasons, among which leaf ulcers are more common!

When the grapes arrive at this season, the leaves turn yellow, which is not a good idea.

AbstractThe plants of Sunshine Rose, whose fruits are easy to turn yellow, are generally weak. The weak plant stops vegetative growth early and turns to reproductive growth, and the nutrients flow back to the tree and fruit early, and the plant will enter the ripening period faster than other normal plants, so the fruit will also ripen earlier, so we see that our own fruit yellow is faster, probably because it ripens earlier than others.

Sunshine Rose grapes are yellow in color What is the reason why the sweetness has not yet come up, and the Sunshine Rose plants that are prone to yellowing are generally weak trees. The weak plant stops vegetative growth early and turns to reproductive growth, and the nutrients flow back to the tree and fruit early, and the plant will enter the ripening period faster than other normal plants, so the fruit will also ripen earlier, so we see that our own fruit yellow is faster, probably because it ripens earlier than others.

Due to the lack of nutrients, the sweetness cannot keep up.

Blackening of the stems of Sunshine Rose grapes can be caused by a variety of reasons, but here are some of the most common causes of eggplant: Pests and diseases: The fruit is attacked by bacteria or insects, resulting in the blackening of the stems.

If you observe other abnormalities on the surface of the fruit, such as spots, rot, etc., it is more likely to be caused by pests and diseases. Insufficient water: Fruits need plenty of water to grow**, and if the soil is dry or not watered enough, it can cause the fruit and the pedicle to lose moisture and turn black.

Insufficient nutrients: If the plant is deficient in certain key nutrients such as potassium, magnesium, iron, etc., it can also cause the fruit to turn black. It is advisable to use appropriate fertilizers to supplement the nutrients needed by the plants.

Weather causes: Extreme weather conditions, such as high temperatures or strong winds, can also have a negative impact on the fruit, causing the fruit to turn black. If you wish to solve this problem, it is recommended that you carefully observe the condition of the plant and fruit and take appropriate measures to deal with it.

If the problem is serious or cannot be treated, consider consulting a professional horticulturist or plant doctor.
