Symptom Identification and Control Methods for Peach Fungal Shot Hole Disease
[Symptoms] When leaves are infected, circular or nearly circular lesions initially appear, with purple edges and slight concentric rings, measuring 1-4 mm in size; later, grayish-brown mold-like growth develops on the lesions, the center dries up and falls out, forming shot holes with neat edges, and when there are many holes, the leaves drop off. When new shoots and fruit are infected, the symptoms are similar to those on leaves. [Disease Development Pattern] [Regional Damage Severity] [Integrated Control] (1) Eliminate the source of inoculum. Promptly prune diseased branches, thoroughly remove diseased leaves, and burn or bury them deeply. Before peach trees bud, spray

Key Cultivation Techniques and Management Methods for American Plumcot
American plumcot, namely the new intergeneric hybrid cultivar of apricot and plum, is a new cultivar introduced from the United States by the Economic Forest Research and Development Center of the Chinese Academy of Forestry. This cultivar was developed through multiple generations of hybridization between apricot and plum. Its fruit has a unique rich and fragrant aroma, and its sugar content is much higher than that of any single apricot or plum cultivar, with soluble solids content reaching 18-20%. It is one of the emerging fruit varieties with the best market prospects. Currently, 7 cultivars have been introduced: Flavor Rosa, Flavor Queen, Flavor Delight, Flavor King, Dinosaur Egg,

Detailed Explanation of Apricot Jam Processing Methods and Production Steps
The process flow is as follows: raw material selection -> raw material washing -> cutting in half, pit removal, trimming -> softening, pulping -> heating and concentration -> canning, sealing -> sterilization, cooling -> inspection -> labeling -> finished product. . Operational key points: (1) Raw material selection: select fresh apricots that are free from pests and diseases, free from mold and deterioration, and at eight-to-nine-tenths ripeness. (2) Washing, cutting in half, pit removal, trimming: for peeling, the lye spraying peeling method can be used. Soak the fruit in a 10%-15% sodium hydroxide solution and boil for 5-10 minutes. After peeling, immediately rinse with a large amount of clean water.

Technical Key Points and Implementation Methods for the Improvement of Abandoned Jujube Orchards
1 Breaking the Hardpan, Deep Plowing, Clearing Weeds and Removing Suckers Deep plowing can clear weeds, remove excess root suckers, and increase the soil's permeability and capacity to retain water and dissolve fertilizers. It can also turn pest eggs and larvae up to the surface to be dried out by the sun or picked out and killed. Deep plowing should be carried out when the soil is suitable for cultivation; if too dry or too wet, clods easily form and the structure is destroyed. Deep plowing should also be adjusted in depth according to position: the area far from the canopy should be deeper, reaching about 20 cm; the area near the canopy should be shallower, about 10 cm. This avoids excessive root damage that would affect tree vigor. Deep plowing creates favorable conditions for root regrowth; because the jujube tree has well-developed horizontal roots with strong outward extension and regeneration capacity, damaging part of the root system will also stimulate the sprouting of more horizontal roots.

Occurrence Patterns and Control Methods of the Pear Buprestid Beetle
The pear buprestid beetle begins eclosing in late April, and in early to mid-May the adults chew an oval-round hole to emerge. After emerging, the adults feed on leaves during the day, rest quietly on the leaves in the morning and evening, and when startled have the habit of dropping to the ground and feigning death. About 10 days after emergence and activity, the adults begin to lay eggs; before laying, they crawl along the trunk and insert their ovipositors into rough, raised cracks in the bark to lay eggs, mostly at the fork junctions of branches and trunks that are 2 years old or older, laying 2-3 eggs per site, with each female able to lay 20-40 eggs. Mid to late May is the peak egg-laying period, and early June is the peak hatching period. After hatching, the larvae first bore into the cortex

At the end of the pear tree flowering period, fruit growers should promptly control the following pests and diseases: For pear gall midge and pear psylla, according to the flowering situation of the pear trees, spray for control promptly when flowering is basically finished. For the pesticide, 10% Shenjian 1500x solution plus 10% Shijia Bichlor 2000x solution can be used. For pear rust and pear scab, spray for control promptly at the end of pear tree flowering. For the pesticide, 15% Fenxiuning 1500x solution or 45% Dason 800-1000x solution, plus 10% Shigao 6000x solution, can be used.

How to control the peach fruit borer? A detailed guide to practical control methods
The peach fruit borer, also known as the peach stem borer or peach spotted borer, is an omnivorous pest found throughout the country. Its larvae damage the fruit or seeds of many fruit trees, including winter jujube, peach, plum, persimmon, chestnut, apple, pear, pomegranate and hawthorn. When fruit is damaged, it becomes filled with insect droppings and rots; in severe cases, the impact on both yield and quality is very great. Control methods: 1. In early spring, scrape the bark and plug tree holes. Use black light traps to kill adult moths. 2. During the adult emergence period and peak egg-laying period, spray a 1000-fold dilution of 50% phoxim, or a 1200-fold dilution of 50% dichlorvos emulsion
