How effective is the Jiaduo frequency-vibration insect-killing lamp at trapping and killing the rice stem borer?
The rice stem borer is one of the important pests in rice production in Wuchang City. In recent years, with changes in rice varieties and warming climate conditions in our city, the occurrence and damage of the rice stem borer have become increasingly serious. According to this autumn's survey, for certain varieties in Wuchang, the average number of insects per 100 steps per mu reached more than 20,000, with the highest in key outbreak areas reaching 60,000, and in some cases more than 100,000. Such insect numbers are rare in history, whether domestically or abroad. In order to further control the damage of the rice stem borer, explore new approaches to its control, and reduce pesticide pollution of rice. This year our city set up at Sun Guanghao's field in Lianhua Village, Wuchang Town

Detailed Explanation of Post-weaning Multisystemic Wasting Syndrome in Pigs (Part Two)
4 Prevention and Control PCV2 is highly resistant to inactivation by many detergents and disinfectants, and the effect of medication is limited. Therefore, it is crucial for pig farms to take measures such as changing rearing techniques, improving hygiene conditions, and reducing stress at different stages, in order to lower the "infection pressure" (including PCV2 and any other pathogens). 4.1 Farrowing Period 4.1.1 All-in/all-out, with thorough cleaning and disinfection between two batches of pigs. 4.1.2 Wash sows and deworm them before farrowing;

Causes of Soybean Sclerotinia Stem Rot and Its Control Measures
1. Symptoms The first thing to catch the eye in the field is the upper leaves of the plants turning brown and dying. Brown lesions continue to develop on the stems of diseased plants, producing white cottony mycelium and white granular material, which later turns black and becomes sclerotia. When the stem of a diseased plant is cut lengthwise, black cylindrical sclerotia are seen arranged in rows inside. After the diseased plant dies, it turns grayish white, the hollow stem cortex often rots into a hemp-fiber-like state, and the sclerotia on the outside of the diseased plant readily fall off. The lesions on the pods are brown, and the pods die rapidly without setting seed, finally turning pale white; lightly affected pods may still set seeds, but the affected seeds are rotted or

Detailed Explanation of Key Cultivation Techniques for Hardstem Honeysuckle
Hardstem honeysuckle, also known as tree-form honeysuckle, is a new variety introduced to our province in the past two years, and is currently cultivated only in small quantities in Zhuanghe and Benxi. The traditional old variety of honeysuckle is vine-form, with scattered branches that trail along the ground, which affects ventilation and reduces yield. The new hardstem honeysuckle variety has a hard main trunk, obvious side branches, and a large number of flowering branches, with a yield 2-5 times higher than the original variety. 1. Cultivation Conditions Honeysuckle has a well-developed root system, is a preferred variety for soil and water conservation, is also an ornamental flower, and is moreover an important medicinal herb. It has cold-resistant and heat-resistant characteristics, and can grow within the range of -2

Canine distemper should not be taken lightly; dog owners must pay attention to prevention
"Canine distemper" is also called distemper, a highly contagious, acute infectious disease caused by a virus, and puppies under 1 year old are most susceptible. Currently there is no specific drug that can cure the disease, the mortality rate is between 50% and 90%, and it can occur in all four seasons. The key points for identifying dogs with canine distemper are as follows: First, body temperature shows a "U"-shaped change. That is, at the beginning of the illness the body temperature often rises to around 40, then returns to normal after 2 to 3 days, with a fever-free interval appearing; after several days, the body temperature rises again, mostly staying at 39.

Occurrence and Control of Stem Base Rot in Schisandra
Stem base rot in Schisandra can cause the stem base of the plant to rot, the root bark to fall off, and eventually the entire plant to die. With the expansion of cultivated area, the occurrence of stem base rot in Schisandra has shown an upward trend. The general incidence rate is 2%-40%, and in severe cases it exceeds 70%, making it a devastating disease. 1. Disease symptoms Stem base rot occurs on Schisandra of all ages, with 1-3 year old plants being the most severely affected. The disease starts from the stem base or the junction of root and stem. In the early stage of the disease, the leaves wilt and droop as if lacking water, but cannot recover,

Which varieties can be used for controlling the rice stem borer (Chilo suppressalis)?
(1) Fipronil. The recommended dose is 1.5-2.5 g active ingredient per mu. The key application points are: spray at the peak hatching stage of the rice stem borer eggs; the field may be kept with or without a water layer. Because fipronil is highly toxic to bees and aquatic organisms, and especially highly toxic to shrimp and crabs, do not use it in bee-keeping areas or shrimp and crab farming areas. If it must be used, it is recommended to drain the field water before application. After a rice field has been treated with fipronil, do not discharge the field water into fish ponds or rivers and ditches. (2) Fipronil + trichlorfon

Codonopsis stems and leaves can be used as livestock and poultry feed
Codonopsis is a precious Chinese medicinal herb; its dried root is used as medicine and has the effects of tonifying qi and nourishing blood, harmonizing the spleen and stomach, promoting fluid production and clearing the lungs. Its stems and leaves were often discarded in the past. However, in recent years, research has found that Codonopsis stems and leaves contain volatile oil, various amino acids, macro- and trace elements, alkaloids, starch, and more. Farmers at the Sifangpa medicinal herb farm in our county dry and grind the stems and leaves, then add them to feed at a ratio of 20-30% to feed pigs, with a clear weight-gain effect. Feeding them to poultry not only increases the egg-laying rate, egg production, and average egg weight, according to chemical

Damage Caused by the Rice Stem Maggot to Hybrid Rice Seed Production and Its Control Methods
The rice stem maggot (Chlorops oryzae Matsumura) is mainly distributed in China in Heilongjiang, Zhejiang, Jiangxi, Hunan, Hubei, Guangdong, Guangxi, Yunnan, Guizhou, Sichuan, Chongqing and other provinces and areas. In recent years it has become one of the main insect pests in rice production in the hilly and mountainous areas of Chongqing, and the losses it causes have exceeded those of some important pests such as stem borers. In hybrid rice seed production, the occurrence of the rice stem maggot seriously affects the development process of rice, thus leading to poor flowering-date synchronization between the male and female parents and affecting seed production

Key points of the soilless short-stem cutting technique for tea plants
Soilless short-stem cutting of tea plants not only saves costs compared with the traditional short-stem cutting with a soil core layer, but also achieves a cutting survival rate of up to 85%, giving it considerable value for wider promotion. 1. Nursery site preparation (1) Plot selection. The nursery site should be close to a water source, with loose soil and flat terrain, and easy to drain and irrigate. (2) Planning. Adjust measures to local conditions, dividing the site into blocks according to the natural drop of the plot. A drainage and irrigation ditch should be dug around each block, 60 cm wide and 40 cm deep. The beds are generally 10-15 m long and 1 m wide, with a working ditch 40 cm wide between beds, and an east-west bed orientation is preferable.
