How to Control Cutworm Pests in Corn Fields
This year is a once-in-a-century year of severe drought. Due to the drought, cutworms have broken out severely in Taiyi Township, Dali City. The cutworm is also called the soil silkworm, earth silkworm, or root-cutting worm. It is a relatively common underground pest. The life cycle of the cutworm is divided into egg, larva, pupa, and adult (moth)

Wheat blossom midge can be controlled by broadcasting pesticide-treated soil at the booting stage
The wheat blossom midge overwinters as mature larvae in round cocoons in deep soil and can remain dormant for many years. In spring, when the soil temperature at 10 cm rises to about 7°C, which is when wheat begins jointing, the larvae break out of their cocoons and move toward the soil surface. In mid-April, wheat enters the booting stage, and the larvae

How to prevent and control wheat sharp eyespot? Early prevention is key
Recently, some individual wheat growers reported that the tips of the wheat turned yellow, small pale yellow spots appeared on the leaf sheaths, and crisscrossing stripe-like yellow markings appeared on the base, commonly known as "flowering stems," with severe cases showing dark brown rot. These are the typical symptoms of wheat sharp eyespot. It is understood

How to prevent and control wheat rosette dwarf disease? Growers should take preventive measures in advance
Symptoms and characteristics of rosette dwarf disease: infected plants have yellow-green alternating stripes on the upper leaves, increased tillering, stunted and dwarfed plants in a rosette-dwarf form, and generally cannot joint or head. Plants infected in early spring show symptoms successively during the green-up stage and jointing stage, with stripes on the heart leaf and a relatively darker green leaf color

How to control take-all disease after wheat turns green?
Wheat take-all disease, also known as black foot disease, is a typical root disease. It can occur throughout the entire growth period of wheat, and the pathogen only infects the roots and the basal 1-2 nodes of the stem. The severity of the disease is affected by many factors. Continuous cropping and repeated cropping make the disease severe; when wheat and summer corn are grown twice a year and continuously for many years, the disease occurs severely; low soil fertility and an imbalanced ratio of nitrogen, phosphorus, and potassium, especially in phosphorus-deficient plots, make the disease severe; rainy springs and high soil moisture are conducive to the disease.

Key Technical Points for Pest and Disease Control During the Autumn Sowing Period of Wheat
The autumn sowing period is the foundation and key to doing a good job of wheat pest and disease control. We hope farmers will seize this favorable opportunity of autumn sowing, adopt effective measures, and carry out pest and disease control work well for soil-dwelling pests, wheat powdery mildew, and other problems, striving to eliminate wheat pests, diseases, and weeds in the bud stage.

Wheat blossom midge control is urgent, growers need to act in time
The wheat blossom midge is a highly concealed and devastating pest. Once it breaks out over a large area, it takes 5 to 7 years to bring it basically under control, so doing a good job of controlling the wheat blossom midge is very important. For this reason, a reporter recently made a special trip to interview

March wheat pest and disease control methods
March is the first critical period for spring control of wheat pests and diseases in our province. The main pests and diseases occurring include wheat sharp eyespot, wheat spider mites, and seedling-stage aphids. In particular, if wheat sharp eyespot in areas with above-moderate occurrence is not effectively controlled, it will cause serious impact on wheat production

Key Technical Points for Pest and Disease Control During the Wheat Sowing Period
Grasping pest and disease control from the autumn sowing period to the seedling stage of wheat is an important technical component for ensuring full and strong seedlings. The sowing and seedling stages of wheat are also critical periods for the control of many pests, diseases, and weeds. If control is not timely, it often results in missing seedlings and broken rows, or weak and diseased seedlings. In response to the pest

What are the control methods for wheat powdery mildew?
In recent years, with the improvement of fertilizer and water conditions in wheat fields and the increase in plant density in high-yield fields, wheat powdery mildew has become increasingly severe year by year. After the powdery mildew pathogen parasitizes wheat, the plant's respiration increases, transpiration intensity rises, and photosynthetic efficiency decreases, seriously affecting the normal
