Seed Treatment, Disease Prevention, and Pest Control
In the past two years, disease prevention has become increasingly important, especially with the rapid spread of wheat rust and soil-borne diseases. The effectiveness of post-emergence chemical treatments has been less than satisfactory. To address this, seed dressing during sowing time can be highly effective in killing pathogens in the soil and on the seed surface. It also helps prevent diseases such as wheat sheath blight, smut, and root rot. The recommended method is to mix 50–100 ml of 3% Funginex with 10–20 ml of 2.5% Celestine, then dilute with 100–150 ml of water for every 10 kg of seeds (equivalent to one mu). Additionally, using 20–40 ml of 12.5% Full-escape Water Suspension Concentrate mixed with 150 ml of water per 10 kg of seeds can further enhance protection. Due to heavy infestation in some fields, a large amount of bacteria accumulates in the topsoil. To reduce disease occurrence, it is advisable to till the soil to a depth of 40 cm during sowing.To control underground pests such as wireworms and grubs, you can use 40% Methyl parathion at a rate of 100 g or 20% Methyl isofosfate at 150 g per 3 kg of water. Mix the solution evenly and spray it onto 50 kg of wheat seeds. After air-drying, the seeds can be sown safely, which helps effectively prevent underground pests.
Using Biogas Slurry for Seed Treatment to Improve Wheat Resistance
Place the seeds in a breathable, durable, and clean plastic bag that allows good water permeability. Since the seeds will absorb water and swell, avoid overfilling the bag. Typically, fill the bag with 15–20 kg of seeds. Submerge the bag into the biogas slurry located in the middle of the digester’s discharge chamber. Place a wooden stick across the discharge port and tie the other end of the rope to the center of the stick to suspend the bag properly. Soak the seeds for about 12 hours. Afterward, remove the bag, drain the slurry, rinse the seeds with clean water, spread them out to dry, and then proceed with sowing. This method can significantly improve the resistance of wheat plants.Selecting Quality Seeds
It is essential to choose high-quality seeds to avoid problems like wheat stem rust, head blight, and smut, which often occur in heavily infected plots. The surface of wheat seeds may carry harmful bacteria, so it's crucial to avoid using harvested wheat for planting. Additionally, weeds such as barnyard grass and wild oats have been problematic in recent years. These weeds are difficult to control due to their strong germination ability and tendency to fall off easily. If they are already mixed with the wheat, they should not be used as seeds.Don't Rush to Control Wheat Midge During Sowing
Controlling wheat midge during sowing is not recommended. When poisoned soil is applied during sowing, the midge larvae, which are dormant at a depth of 15–20 cm, remain inactive and do not interact with the outside environment. They are protected by a layer of earthworms, making the treatment ineffective. The two critical periods for controlling wheat midge are: first, applying poisoned soil during the flood season, usually around mid-April; second, spraying adult midges, typically in early May. Proper timing is key to achieving effective control.Aluminum Foil Net,Knitted Aluminum Heat Shield,Full Shading Reflect Net,Insulating Aluminum Foil Mesh
