What s the deal with sticky sap from fruit tree branches and leaves?

You look at the back of the leaves. Is there a large number of aphids? Because this period is the time when aphids multiply in large numbers, if you don't pay attention to control.

It's going to happen. Metabolites of toothworms. Fall on the blades on top.

More and more are accumulating. Whole blades. It's all bright and shining.

Some of them will drip down if they are too much. If you don't mind. You can lick it with your tongue.

Its taste is sweet. It tastes like honey. If you find this situation, hurry up and control aphids, it can be made.

Fruit tree yields have been severely reduced. Reduced quality. Impact on revenue.

1.Climate: Continuous high temperature, excessive transpiration of branches and leaves, resulting in rapid loss of water and green of leaves.

After a rainy day, it suddenly becomes sunny, which is also very easy to cause an imbalance in water metabolism, which leads to dry leaves, etc.).

2.Tree potential: old trees, weak trees, diseased trees, trees with too many fruits, and vigorous trees are prone to this situation, and old trees have tissue aging and reduced resistance; Weak trees have insufficient nutrients and poor ability to resist high temperature stress; Diseased trees such as canker, rot, gum disease and other branch diseases will lead to obstruction of fertilizer and water delivery; There are too many fruits, the nutrients of the tree body are concentrated for the fruit, the branches and leaves retain less nutrients, and the resistance is poor, so the old, weak, sick and other trees are prone to dry leaves, fallen leaves, and dry branches.

3.Roots: The growth of the root system corresponds to the branches and leaves, if there is root rot, the aboveground part will appear wilted, wilted, dry leaves, dead branches, etc., especially the root tip, if the root tip activity is reduced or damaged, it will lead to the wilting and death of young shoots and young leaves.

Soil conditions, management and other factors affect the growth of the root system.

Second, the solution:

1. Leaf protection: spray Liangguoan 150 times + garlic oil 1000 times + amino acid foliar fertilizer 1000 times 2 times, with an interval of 3-5 days.

Function: sterilization, repair wounds, replenish nutrition, increase chlorophyll content, make young leaves cork (thicken waxy layer).

2. Root raising: R. solanacearum 200 times + Trichoderma harzianum 200 times root irrigation 1 time.

Purpose: Protect rhizosphere microenvironment; Promote rooting; Improve the soil.

3. For branch diseases, such as canker, gum disease, and rot disease, brush dry with the original solution of ulcer rot, and at the same time cooperate with the above leaf preservation and root raising schemes to carry out three-dimensional prevention and control of upper spraying, lower irrigation, and middle brushing.

Flowing gum is a common disease on Rosaceae and Rutaceae fruit trees, especially on citrus, peaches, apricots, plums, cherries, and apples, which has a great impact on the tree's potential, and the yield and quality of fruit trees are also frustrated, and even cause the destruction of the entire orchard when the disease is serious.

In the early days, the flow gum was often misunderstood as wound flow or considered a simple physiological disease, but with the deepening of research, people found that the cause of flow gum is more complex, and biological factors can also lead to the occurrence of flow gum, this time we will talk about this topic in detail.

All kinds of fruit trees, all kinds of flowing gum.

Plum tree flow gum. The physiological flow gum of fruit trees usually appears on the main trunk or main branch, which is nearly transparent and viscous at the beginning, and the tree tissue is obviously damaged at the flow gum.

Cherry flow gum. After a period of contact with air, the gum is oxidized and becomes a brown hard amber gum block.

Citrus flow gum. After the gum flow occurs in the tree, it is easy to be infected by saprophytes, and the diseased part accelerates the ulceration, and the tree deteriorates.

Peach tree flow gum. There is also a type of nodulous protrusion on the branch in the previous year, and then cracking and flowing gum in the next year, and there is a peak occurrence, and there are black dot-like lesions at the flow gum, which belongs to the category of infectious flow gum.

The secret of fruit tree gelatin.

The occurrence of physiological gel flow usually starts when the tree is damaged or wounded. Of course, the damage to the tree body here refers specifically to the molecular level, for example, if the tree has been subjected to adverse environmental stresses such as frost damage and burning, the organelle membrane structure has been irreversibly damaged; Mechanical damage caused by fruit tree pruning, typhoons, hailstorms, dry-boring pests, etc., can also induce gum flow.

The pathogenic bacteria of infectious gelatinous flow are mainly fungi, such as Phyleta vulgaris, Phytophthora fungi, Stemic Pseudostem Spotted Mold and Fusarium oxysporum. Some bacteria can also induce gum flow, such as Pseudomonas syringae, bacterial canker bacteria, etc.

The main differences: physiological gel flow is more occasional, and there is a certain regularity in infectious gel flow, such as after the infection in the previous year, there are two incidence peaks in May, June, August and September in the next year; Infective flow gum is not wound-dependent and can invade through the cutaneous pores, but the presence of the wound will make it easier for germs to enter.

Similarities: The symptoms are extremely similar, and the later stage is all glue and ulceration; The pathogenic mechanism is similar, which is due to the excessive synthesis of gum polysaccharides caused by the sharp increase in ethylene levels. In terms of occurrence conditions, the weakening of the tree will aggravate its occurrence.

Secretion. Dioecism. The female has no wings, and the male has 1 pair of membranous forewings, and the hindwings are specialized as balance rods.

Scale insects are the most common pests of flowers, often clustered on branches and leaves. Adults and nymphs use needle-like mouthparts to insert into flower leaves and branches to absorb the juice, causing branches and leaves to wither, and even the whole plant to die, and can induce coal stain disease, which is extremely harmful.

2. Aphids, also known as honey worms, greasy insects, etc., mostly belong to the family of homoptera aphids, are pests of stinging and sucking mouthparts, often clustered in leaves, young stems, flower buds, apical buds and other parts, sucking sap, making the leaves shrunk, curled, deformed, and in severe cases, causing branches and leaves to wither and even die of the whole plant. The honeydow secreted by aphids can also induce coal stain disease, viral diseases and attract ant damage.

3. Drug**: 40% dimethoate can be used 1000 times liquid, sprayed once every 7-10 days, 2-3 times in a row.

Phaseolus vulgaris is the "happy tree", the scientific name of the bean tree, which likes high temperature, humidity and sunny environment. High temperature resistance, cold resistance, should be moist, avoid dryness. Loose, fertile, well-drained, organic-rich loam and sandy loam soils should be used for cultivation.

The flowering period is from May to September, and the fruiting period is from October to December.

Roots, leaves, and fruits can be used as medicine, which can cool blood and reduce swelling, treat high fever, bruises, and poisonous snake bites. The wood is yellow-brown, slightly coarse and heavy, with obvious growth rings, which can be used as building timber. Branches, leaves and roots also cure bovine anthrax.

You look at the back of the leaves. Is there a large number of aphids? Because this period is the time when aphids multiply in large numbers, if you don't pay attention to control.

It's going to happen. Metabolites of toothworms. Fall on the blades on top.

Hello! The mango leaf juice gets on your clothes and can be washed in the following ways:

1. If it is a fresh stain, rinse off the surface stain with cold water, if it is an old stain, when the clothes are dry, use Blue Moon hand wash or deep cleaning laundry detergent stock solution to apply to the stain, completely cover the stain, let it stand for 5 minutes (can be gently scrubbed), add Blue Moon laundry detergent for regular washing;

2. If the stain cannot be removed after the above methods, then.

1) Clothes made of white cotton and linen polyester: Add 1 bottle cap (40g) of blue moonshine and white clothes (600g specification) to half a basin of water (about 2 liters), stir well, soak in white clothes for 30 minutes, rinse clean. If there is still no stain after soaking for 2 hours, take out the clothes, add 1 cap of this product to the basin, stir well, put in the clothes and continue soaking.

The cumulative soaking time should not exceed 6 hours.

2) White clothes of color and other materials: put the clothes into the basin, the stained parts are attached to the bottom of the basin, measure 1 4 caps (10 grams) of colored clothes and 1 4 caps (10 grams) of blue moon collar with blue moonlight color clothes (600g specifications) with bottle caps, pour them on the stains, cover the stains with other non-stained parts of the clothes, prevent air drying, let stand for 2 hours, and rinse clean. If the stain remains unremoved after 2 hours, it can be left on for an extended period of time overnight.

Precautions: White clothes are suitable for white cotton, linen, polyester, polyester cotton, cotton and linen fabrics, do not use silk wool spandex nylon and other non-chlorine bleaching clothes, do not directly use the original solution. Colored clothes are not suitable for clothes that are easy to fade and dry cleaning, avoid touching metal buttons, zippers, metal ornaments, etc. on the clothes when using, and avoid direct sunlight.

You can soak your clothes in salt before washing them, so that the dirt can be easily removed.

Method 1: Freshly stained, you can use table salt to rub on the stain (let the juice adsorb on it) - moisten it with water - wash it with soap. Method 2:

If it is already dry, rub it with white vinegar - let it sit for 5 minutes - and then wash it with water. Method 3: Baking soda melts with water - scrub.

The last trick is also a strange trick: colored fabrics are washed with concentrated salt water in turn, washed with water, kneaded with 10% ammonia, and washed with detergent; White fabrics can be soaked in bleach solution (3% 5% sodium hypochlorite solution) for l 2 hours and then rinsed with water. In addition, it can also be rinsed with salt, and the effect is also good Salt is sold in large supermarkets

The shorter the stain stays on the garment, the easier it is to remove. In addition, the type and size of the stain and the material of the garment will affect the stain removal effect.

It is recommended that you try the Radial Clean Nu Skin laundry detergent, which contains stain autolysis technology to remove dry stains, and is gentle on the body, easy to dissolve and rinse, and can also care for the color of the fabric. For heavy stains, it is recommended to apply an appropriate amount of laundry detergent directly to the stains, and let it stand for about 5 minutes before washing to achieve a better cleaning effect. It is recommended to extend the soaking time appropriately according to the degree of dirtiness of the clothes, or wash with warm water for better results.

Of course, when washing, please pay attention to the laundry label of the clothes and wash them as required to avoid damage to the clothes.

Apple powdery mildew. That is, the leaf edge is curled upwards and covered with white powder. Spray stone sulfur mixture once eight days before flowering at bud germination stage and once after flowering.

The concentrations are 3 to 5 °, to, to. It can also be sprayed with 25% powder rust 1000 times liquid, 70% non-tozine 1000 times liquid.

Saved.

Heavy rains across the country have brought a lot of losses to many fruit farmers. In particular, some low-lying terrain has poor drainage, and the orchards of clay and clay loam are more waterlogged, and the waterlogging of sand and sandy loam is relatively light. In severe cases, it will cause yellowing of leaves, leaf loss, fruit drop, nutrient deficiency, root rot and death.

Therefore, after the flooding, it is necessary to take timely countermeasures to minimize the loss of the orchard.

1. Remove stagnant water.

The degree of damage caused by waterlogging to fruit trees is directly proportional to the length of soaking time. The longer it passes, the more damage the fruit tree will suffer. It is necessary to immediately organize manpower to quickly open and dredge ditches to lower the groundwater level of the orchard.

A small area of stagnant water can be manually discharged, and a large area of stagnant water should be combined with mechanical multi-point drainage to prevent long-term stagnant water and root rot. For plots that often accumulate water, it is necessary to dig more drainage ditches to ensure that the ditches are connected and the drainage is smooth.

2. Appropriate pruning.

After waterlogging, the photosynthetic efficiency of the plant is low, and the ability of the root system to transport nutrients and water is weak. At the same time, some excessively long branches should be appropriately retracted, and some small fruits should be removed to reduce the load of fruit trees. For fruit trees with serious waterlogging, long water accumulation time, and serious root damage, the amount of pruning should be increased, and the method of heavy stubbing or even retraction can be used to ensure the survival of fruit trees.

3. Fruit tree cleaning and reinforcement.

After the rainstorm and strong wind, the root system of the plant is damaged, easy to lodging, after drainage should be straightened in time, for the inclined tall fruit trees, timely straightening and standing pillars fixed. Prevent root damage caused by re-tilting. Clean up the silt on the surface of the plant to ensure the normal photosynthesis of the leaves and promote the growth of the plant.

4. Turn over the soil and dry the roots.

Remove the silt around the tree disk, remove the soil of the root neck and thick root part to dry the roots, prune and remove the rotten root system, promote the volatilization of soil moisture, increase the oxygen content of the soil, improve the beneficial microbial activities of the soil, restore the development of the root system, and promote the growth of the root system. Pay attention to the depth of the soil should be appropriate when turning the soil, so as not to hurt the root system of the plant.

5. Supplement tree nutrition.

After the plant is flooded, the soil nutrient loss is serious, and the root system has a weak ability to transport nutrients and water, so the root topdressing should be carried out in time. Due to the high moisture of the soil, foliar fertilizer should be sprayed appropriately and effectively. At this time, a comprehensive supply of nutrients should be carried out, that is, macronutrients, medium elements and trace elements should be supplemented.

At the same time, the use of amino acid foliar fertilizer to improve the photosynthetic efficiency of leaves and strengthen the stress resistance of plants. After the plant has resumed growth, the roots are fertilized.

Because of orange peel, orange peel soaked in water and fermented is an acidic fertilizer, which is not recommended to be used as foliar fertilizer, and can be fertilized by roots.

Instead of spraying on the leaves, it sucks fertilizer to the roots. You see its roots absorb nutrients.

The goat's milk fruit is a plant of the family Euphoraceae, Honey Flower, Elata gnus, Contetaroxbof ripe fruits. Perennial evergreen climbing shrub, ripe fruit bright red to purple-red, fresh fruit raw food, edible part accounts for 91%, sweet and sour, moderately delicious, sufficient moisture, bright color, can be used as juice, canned, preserves.

Goat milk fruit leaves are spotted or insect pests, goat milk fruit planting should be timely weeding and topdressing fertilizer to promote the growth of seedlings, after 1 2 times of weeding every year, after the forest is cut off in autumn too dense branches, can be managed according to the shape of the bush branches, cut off the drooping branches and tillers, keep ventilation and light, and enter the fruiting period after 3 years.
