The planted pomegranate tree has a lot of white spots on it, what should I do?

In this case, it must be a white pest and disease, in which case some pesticides should be sprayed to solve it, and the dose of spraying should be mastered, and it will slowly disappear.

The planted pomegranate tree has a lot of white spots, it must be infected with pomegranate powdery mildew, first of all, we must strengthen the fertilization and cultivation of branches and leaves, improve the ability to resist disease, and buy a little chemical agent to prevent and control.

Pomegranate trees should be pruned in time in summer to improve ventilation and light transmission conditions and reduce the occurrence of pests and diseases. Do not use dimethoate and dichlorvos pesticides to control pomegranate tree pests, because pomegranate trees are sensitive to these pesticides.

The pomegranate tree has white spots and is a scale insect.

It can be sprayed with scales.

Pomegranate cultivation techniques.

It can be planted or repotted after the leaves fall in autumn and before budding in the spring of the following year. Ground planting should be selected in a sunny, leeward, slightly high place, and the soil should be loose, fertile and well-drained. The potted plants are made of humus, garden soil and river sand, and an appropriate amount of well-rotted organic fertilizer is added.

When planting, it is necessary to bring soil mass, the above-ground part should be properly shortened and trimmed, watered thoroughly after planting, placed in the shade for maintenance, and moved to a ventilated and sunny place after germination and survival.

Light, light and temperature are important conditions for flower bud formation. The growing season requires full sunshine, and the more sunlight there is, the more flowers will be more vivid. The leeward, sunny, dry environment is conducive to flower bud formation and flowering.

When the light is insufficient, it will only grow leaves and not bloom, which will affect the ornamental effect. The suitable growth temperature is 15 to 20, and the winter temperature should not be lower than minus 18, otherwise it will be frost damaged.

Water and fertilizer pomegranate ground planting must be reapplied organic fertilizer once a year, potted plants need to be repotted and fertilized for 1 to 2 years. In the growing season, top dressing should also be carried out 3 to 5 times, and pay attention to loosening the soil and weeding, and often keep the potting soil moist to prevent drought and waterlogging.

Trimming pomegranates needs to be trimmed every year; It can be formed into a single-stem round-headed shape, or multi-stem bush formation, or it can be forcibly trimmed into a dwarf flat-headed crown. In the fruiting period, the long branches should be topped in summer and truncated in autumn to avoid the occurrence of secondary branches and tertiary branches at the top, so that they can store nutrients in order to form the fruiting mother branches in the next year, and at the same time, the germination and tillering in the rhizosphere should be cut off in time.

Wintering in the cold regions of the north, in winter should be in the cold room or cellar to protect against the cold.

Harvested pomegranates bloom 3 times a year, so there are 3 fruits, and generally the first flower fruit or second flower fruit grows well. It should be harvested in stages according to the characteristics of the variety, fruit ripeness and climatic conditions. The signs of pomegranate fruit ripeness are:

The peel turns from green to yellow, the colored varieties are fully colored, and the fruit surface appears shiny.

The fruit ridge is revealed. The red or silvery-white needles in the pulp cells are fully visible.

The kernels are plump and the fruit juice has a soluble solids content that is intrinsic to the variety. Ripe fruits are harvested before the rain, and harvesting is prohibited in rainy weather.

Seedlings propagated by cuttings or ramifications begin to bear fruit after 3 to 4 years of planting, while seedlings propagated by seeds take more than 10 years to flower and bear fruit.

Fruit preservation first, in the early stage of fruit growth from May to July, irrigation should be carried out many times to maintain the most suitable humidity of the soil, and after irrigation, grass or film mulching to protect moisture, so that the fruit grows at a uniform speed.

Second, in the later stage of fruit growth (the rainy season in August and September), it is necessary to stop irrigation, remove excess water in time, maintain moderate soil humidity, and prevent the fruit from cracking due to excessive water absorption.

Thirdly, the measures of bagging young fruits can not only prevent the harm of diseases and insects, but also maintain a good humidity in the fruit bag, so that the fruit grows at a uniform speed, and prevent the rainwater in the rainy season from directly soaking into the fruit, causing the rapid growth of the grains, resulting in the expansion and cracking of the peel.

Fourth, harvest ripe fruits in time to prevent the peel from swelling due to excessive water absorption.

Now there are two possibilities, one could be powdery mildew, on the leaves.

One may be on the rod and is a scale insect that, if pinched, shows red.

The former is a disease, and rust can be treated.

The latter is a pest and requires a special drug to kill scale insects**.

Pomegranate trees with white spots and trichlorfon insecticides can prevent pests!

The planted pomegranate tree has a lot of white spots on it, what should I do?

The planted garnet hail tree has a lot of white spots on it, what should I do? Hello, commonly known as "tree lice", can be used to kill the enemy, methamidophos, gram mite and other drugs to prevent and control. Scale insects reproduce quickly and in large numbers, and begin to feed in March and April.

If the balcony pot is planted, the most effective and trouble-free way to remove it is to take a wet rag and wipe it vigorously. For large-scale planting, you can take 5-6 cigarette filters, soak them in 2 catties of water overnight, remove the cigarette filters, add soybean-sized laundry detergent, fully stir, and spray. Once a week, spray 5-8 times in a row.

It is caused by scale insects.

Also known as "scale insects", scale insects are often male wings and can fly, and female and larvae once feathered, they live on branches and leaves or fruits for life, causing yellowing of leaves, wilting of branches, decline of tree potential, and easy to induce coal pollution disease.

Control methods: 1. Regular fertilization to enhance the strength and resistance of trees; Combined with maintenance management, overwintering nymphs on branches and stems were manually brushed in autumn; Concentrate on burning the dead plants to completely eliminate the source of insects to avoid transmission; Strengthen pruning, ventilation and light, and reduce the incidence of insect infestations.

2. According to the morphological characteristics of scale insects, the first choice for the prevention and control of this kind of pests is the agent with super systemic and osmotic effect, such as "scale must be treated" 750 1000 times liquid spraying, after the liquid is absorbed by the tree, the scale insect sucks the poisonous tree sap and dies, and the insecticidal effect is good.

Now there are two possibilities, one could be powdery mildew, on the leaves.

One may be on the rod and is a scale insect that, if pinched, shows red.

The former is a disease, and rust can be treated.

The latter is a pest and requires a special drug to kill scale insects**.

Pomegranate trees will grow black and rotten spots at the peak fruiting stage, and they can fall off soon, which is mainly caused by grenadine brown spot disease.

The leaves are small black-brown spots at first, nearly rounded after expansion, the edges of the lesions are black to black-brown, slightly convex, and gray in the middle; The symptoms on the back of the leaf are the same as those on the front, the lesions on the fruit are nearly round or irregularly shaped, black and slightly concave, and there are also gray velvety small spots, and the outer edge of the lesions is pale yellowish white after fruit coloring.

The prevention and control measures are:

1. Strengthen cultivation management, reasonable pruning, and enhance tree potential;

2. Clean the orchard, and burn or bury the fallen leaves and fruits in the orchard after the leaves are dropped;

3. For the prevention and control of pesticides, 140 times the equivalent Bordeaux solution or 80% ultra-micro carbendazim solution can be sprayed once in the early stage of the disease.

Pomegranate trees grow black spots at full fruiting and soon fall off, mainly caused by pomegranate brown spot. The leaves are small black-brown spots at first, nearly rounded after expansion, and the edges of the lesions are black to black-brown, slightly convex, and gray-brown in the middle; The symptoms on the back of the leaf are the same as those on the front, the lesions on the fruit are nearly round or irregularly shaped, black and slightly concave, and there are also gray velvety small spots, and the outer edge of the lesions is pale yellowish white after fruit coloring.

3) For the prevention and control of pesticides, use 140 times the equivalent Bordeaux liquid or 80 ultra-micro carbendazim solution to spray once in the early stage of the disease, and the control effect can reach more than 80, and the effect is better if sprayed 3 times in a row.

Do pomegranates bear now? I'm afraid it's been a long time.

Summary Processing Method:

1. Cut off insect branches or brush insect bodies.

2. Spray diesel emulsion with 10% oil content just before falling leaves or germination, if mixed with chemicals, the effect is better.

Potted pomegranate trees have white stains that are pests.

Hello, it's a pleasure to be able to serve you. As far as I know, it's a kind of turtle wax scale, a scale scale insect. Its excrement can also induce the occurrence of soot disease, which makes the plant densely covered with black mold, which directly affects photosynthesis and leads to poor plant growth. It must be dealt with in a timely manner. 

Treatment method: 1. Cut off insect branches or brush insect bodies. 2. Spray diesel emulsion with 10% oil content just before falling leaves or germination, if mixed with chemicals, the effect is better.

My pomegranate tree also has such insects, I think it is more convenient to take a wet rag, wipe vigorously, so that the insect can be removed relatively quickly.

It's my pleasure to help you, and I hope I help you
