Symptom Identification and Integrated Control Methods for Strawberry Bud Blight
Strawberry bud blight is a soilborne fungal disease with a worldwide distribution. It is strongly saprophytic in soil and is an important root disease of many crops. In addition to strawberry, it also affects more than 160 species of cultivated and wild plants, including cotton, soybean and vegetables. On strawberry, it mainly damages buds, new shoots, stipules and the bases of leaf petioles, causing seedling-stage damping-off...

Key Integrated Pest and Disease Control Techniques for Onion Seedlings
I. Selecting Superior Varieties In production, purple-skinned varieties such as Ziyu No. 1, Ziyu No. 2, Zixing, and Shuanghuanhong can be selected. These varieties have the characteristics of strong pungency, high yield, excellent quality, and suitability for export. These varieties generally yield about 5000 kg per mu, and high-yielding plots can reach 7500 kg per mu. II...

How to prevent and control watermelon seedling diseases? A detailed guide to integrated control techniques
I. Symptoms of the main diseases 1. Damping-off. In the early stage, the root collar of the seedling (the junction of root and stem) develops lesions that look as if scalded by boiling water and become rotten, after which the diseased part turns yellowish-brown, dries out and shrinks; the cotyledons have not yet wilted, but the seedling topples over. Damping-off mostly occurs from the emergence of the cotyledons to the stage when 2 true leaves have flattened out. The disease spreads very quickly; a few days after the appearance of the first diseased plants, seedlings topple over in patches. Under conditions of high temperature and high humidity, the diseased parts of the seedlings and the ground nearby,

Integrated Control Methods and Technical Key Points for Walnut Branch Blight
Walnut branch blight is caused by fungal infection and mainly damages branches and trunks. It occurs in all regions, with a general diseased plant rate of 20-30%, and in severe cases the diseased plant rate reaches over 80%, causing massive branch dieback and directly affecting tree growth as well as walnut yield and quality. Therefore, timely control is necessary to curb the disease and promote tree...

How is integrated control of lotus root diseases carried out?
I. Lotus root brown spot disease A common disease of lotus leaves, producing light brown lesions on the leaves, causing localized drying of the affected leaves. Control: Reasonable close planting to ensure ventilation and light penetration in the lotus field; appropriately increase the application of phosphorus and potassium fertilizers to improve plant resistance, and promptly remove diseased plant residues. At the early stage of the disease, use 25% carbendazim 600x solution, or 75% chlorothalonil...

Key Technical Points for Integrated Pest and Disease Control in Chinese Yam
I. Agricultural Control 1. Selecting disease-resistant varieties is an effective method for controlling Chinese yam pests and diseases. When cultivating disease-resistant varieties, rational layout is necessary, rotating varieties every 2 to 3 years, and attention should be paid to variety purification and rejuvenation. 2. Crop rotation can reduce or avoid damage from Chinese yam stem rot and root-knot nematodes. Rotate at least once every 3 years with crops that are not infected, such as corn (2343, -3.00, -0.13%), wheat, radish, and watermelon; in old areas where Chinese yam is cultivated year-round, rotate once every year; where conditions permit, paddy-upland rotation can be implemented for better control results.

What are the integrated control methods for wheat take-all disease?
Wheat take-all is a typical root disease, capable of infecting wheat from sowing through to harvest. The main sites of infection are the wheat roots and the 1st to 2nd nodes of the stem base. After infection by the pathogen, the roots turn black and rot, losing their ability to absorb water and nutrients, which causes the above-ground parts to dry up and die, resulting in white heads. 1. ...

Integrated control of peanut pod rot to achieve both higher yield and better quality
Peanut pod rot, also known as "peanut rotten pod disease," has become fairly common in recent years in the major peanut-producing areas of our province, including Daming, Xinle, Dingzhou, Xingtang and Luanxian, and it becomes even more severe in fields planted continuously to peanuts for many years when the pod-setting stage coincides with a rainy year. According to surveys, affected fields suffer at least a 20% yield loss, ...

Integrated control methods for three pests of spring soybean
I. Cutworms. The main pest damaging local crops is the yellow cutworm (Agrotis segetum). 1. Damage characteristics: The larvae mostly bite off seedlings at ground level, causing missing plants and broken rows. After the main stem becomes lignified, they feed on the epidermis of the roots near the ground surface, causing root damage that affects the root's ability to absorb water, causing the plant to gradually wilt and die. ...
