Diagnosis and treatment of hemlock poisoning in livestock
Hemlock, commonly known as wild celery, is a perennial umbrella plant, like to grow in wet, low-lying areas, toxic mainly in the root and stem, the component is alkaloid apigenin. Because hemlock germinates earlier and grows faster than other plants in spring, when cattle and sheep graze in low-lying areas in early spring, cattle and sheep first see hemlock seedlings and immediately eat, and gnaw off the rhizome exposed to the ground, because its rhizome is less sweet, cattle and sheep like to eat, to a certain amount, causing poisoning. 1. Clinical symptoms occur suddenly during grazing, showing agitation, shortness of breath, rumen dyspnea and abdominal pain.

Pollution-free prevention and control of pepper blight

The peak incidence of sweet (spicy) pepper blight cultivated in the open field is from the middle of July to the end of August, which is a fungal disease, and the incidence of vegetable field is more than 85%. The pathogen has a short incubation period, rapid infection and rapid spread. if it is light, it will reduce production by 30%. In severe cases, it will die in a large area, with a dead plant rate of 20% to 80%, or even no production, resulting in devastating disasters. Symptoms: there are obvious central diseased plants in the disease area, plant wilting at the initial stage of the disease, leaves and fruits do not fall off, do not change color, careful observation can find the plant
