What are the main storage-period diseases of garlic scapes and garlic bulbs?
In Jinxiang County, Shandong Province, the garlic planting area has been around 500,000 mu in recent years, accounting for 40% of the county's cultivated land area. The county has 700 large and small constant-temperature warehouses, with a storage capacity of 450,000 t. Every year from late April to early-to-mid May, garlic scapes and garlic bulbs are harvested in a concentrated period. Apart from a small amount consumed locally or shipped out, most of the garlic scapes and garlic bulbs are stored. Losses occur during storage, and rot caused by various diseases is the main cause of loss during the storage of garlic scapes. 1 Diseases of garlic scapes during storage 1.1 Gray mold 1.1.1

What should be noted when harvesting garlic scapes?
Generally, when the garlic scape emerges from the leaf sheath and begins to bend, it is the suitable time to harvest the garlic scape. Harvesting early or late has a great impact on the yield and quality of the garlic scape. If harvested too early, the yield is not high, it breaks easily, and its marketability is poor. If harvested too late, although the yield can be increased, it consumes too many nutrients and affects the growth and development of the garlic bulb, and the garlic scape tissue ages and its fiber increases; especially the base of the garlic scape ages and becomes inedible. Therefore, it is best to harvest garlic scapes at noon and in the afternoon on sunny days. At this time the plants are somewhat wilted, the leaf sheath and the garlic scape separate easily, and the leaves are tough and not easy to break, which can

What causes secondary branching and deformed scapes in garlic? Here's how to prevent it
Every year during the scape-elongation stage of garlic, a certain proportion of garlic plants develop secondary branching and deformed scapes, seriously affecting the yield and quality of garlic scapes. In recent years, we have carried out investigations and research, and have explored effective agricultural measures to control the occurrence of secondary branching and deformed scapes in garlic, which have played a very significant role in improving the economic benefits of garlic growers. 1 The harm caused by secondary branching and deformed scapes in garlic. Secondary branching in garlic is also called secondary growth or branching, and growers call it "horsetail garlic". There are generally two phenomena: first, branches differentiate from the outer leaf sheath,

How to Store and Keep Garlic Scapes Fresh: Methods and Techniques Explained
Garlic scapes, commonly known in some places as garlic sprouts, are the flower stems that bolting garlic produces after vernalization, and they are an important by-product of garlic production. Garlic scapes are rich in crude protein, a variety of vitamins and minerals, and have a delicious flavor, making them a high-quality, premium vegetable. (1) Storage conditions 1. Temperature 0-0.5°C. 2. Relative humidity 90%-95%. 3. Gas composition O2: 2%-4%, CO2: 6%-8%. (2) Storage methods 1. Ice cellar storage method: trim the selected garlic scapes

What control measures should be taken when pathological changes occur in garlic scapes during storage?
Abnormal changes of the scape tip 1. Browning of the scape tip (1) Symptoms The scape tip changes from yellow-green to yellow-brown or dark brown, dehydrates and shrinks into a thin flake-like form, is prone to decay, and is easily infected by mold, losing its toughness; dry-affected ones break easily, and wet-affected ones rot easily and are infected by mold. (2) Causes The tissues of the scape tip undergo physiological aging and death, and lose water and shrink. High temperature and high oxygen promote browning, and high humidity aggravates the degree of browning. (3) Control Harvest at the proper time, and strictly prevent high temperature, air-drying, or smothering during harvest and transport.

Proper drought and disease prevention management during the garlic scape development period
The garlic scape development period is the reproductive growth stage of garlic, mainly including the flower bud differentiation stage and the scape elongation stage. The differentiation of flower buds and bulbils is a critical period in garlic growth and development, and smooth differentiation helps increase yield. The scape elongation stage refers to the period from when the scape begins to elongate until the scape is harvested after the tail-flicking stage, about 30 days. During the garlic scape development period, flower bud differentiation requires temperatures below 10°C; the scape elongation stage requires an optimal temperature of 12°C-18°C. If the temperature is too low, the scape elongates slowly, affecting yield; if the temperature is too high, the scape elongates quickly, the fiber content increases, and quality deteriorates.

How to harvest garlic scapes? Remember these four tips
In recent years, many garlic farmers have changed the past cultivation method of growing green garlic and digging up green garlic for market into the cultivation method of harvesting garlic scapes and digging up garlic bulbs for market. Among them, quite a few farmers, because they do not know how to harvest garlic scapes scientifically, end up with poor-quality garlic scapes, low yields, small garlic bulbs, and large reductions in output. To help garlic farmers both harvest high-quality, high-yield garlic scapes and achieve the good benefit of a bumper garlic bulb harvest, here are four "tips" for scientifically harvesting garlic scapes. 1. Choose the right harvest time when the "scape tip" bends nearly a full circle. When harvesting garlic scapes, you must

What is the carbon dioxide toxicity physiological disorder in garlic scapes?
When garlic scapes are packaged in plastic film bags, the carbon dioxide level becomes too high in the later stage, often causing toxicity. It shows as yellow spots on the scape stalk, which gradually sink in, join together, and the tissue becomes necrotic, with water-soaked rot, ultimately causing the garlic scapes to break apart. Sometimes the scape bulbAlso becomes necrotic, giving off an alcoholic smell accompanied by a foul odor. In severe cases, the entire bag of garlic scapes rots, and this has become an important disease in garlic scape storage. In controlled atmosphere storage of garlic scapes, carbon dioxide generally should not exceed 5%, and ventilation should be carried out regularly; in the later stage, carbon dioxide exceeding 13% will cause toxicity.
