Symptoms and Control Methods of Bacterial Shot Hole Disease in Peach
[Distribution] It occurs throughout the country, especially in coastal areas, lakeside areas, orchards with poor drainage, and rainy years, often causing severe outbreaks. If control is not timely, it can easily cause massive leaf drop, reduce nutrient accumulation, and affect flower bud formation. It not only weakens tree vigor and reduces the yield of the current year, but also affects fruiting in the following year, resulting in poor harvests. [Symptoms] Water-soaked, pale yellow small spots appear on the leaves, then expand into red round spots, and subsequently turn brown, with the edge darker than the center. Around the edge there is a semi-transparent pale yellow halo. The edge is prone to forming an abscission layer, creating round shot-hole spots. When several lesions join together, the shot-hole shape becomes irregular; in severe cases, a single leaf may have dozens of lesions, and diseased leaves fall early.

How to store garlic? Three simple and practical methods to teach you
Garlic belongs to the Amaryllidaceae family (allium genus) and is a bulb vegetable of the onion-garlic category. By color, it is divided into white-skin garlic and purple-skin garlic. Garlic is cold-tolerant; it can be sown from February to April in early spring and harvested from June to July; when sown in autumn and overwintered in the open field, it is harvested from May to June the following year. After storage, it can be supplied to the market year-round. Storage characteristics: when the garlic scapes have been harvested for about 20 days, and about 1/2 or 2/3 of the leaves have turned yellow and the bulbs are fully swollen, this is the suitable harvest period for garlic bulbs. Irrigation should be stopped 3 to 5 days before harvest to reduce soil moisture and improve bulb quality and storability. Garlic has an obvious physiological

A new method for keeping garlic fresh, teaching you to store it longer
5-10 days before harvesting garlic, spray the basal leaves with a 0.2% maleic hydrazide (MH) sprout inhibitor. The MH sprout inhibitor is absorbed through the leaves and transferred to the young sprouts of the garlic cloves, thereby inhibiting their growth and achieving the purpose of keeping them fresh. With this method, garlic can be stored until April of the following year. The following points should be noted when spraying the chemical: 1. Do not water for 3-4 days before spraying the solution. If rain occurs within 24 hours after spraying, immediately re-spray the solution once at the original dosage after the weather clears. 2. Strictly control the concentration of the maleic hydrazide (MH) sprout inhibitor, which must not exceed 0.
