Description

Technical Field

[0001] The invention relates to the technical field of wheat planting, and in particular to a method for weeding and preventing diseases and insects in wheat fields at the same time. Background Art

[0002] As one of the most important food crops in the world, wheat is often threatened by weeds, diseases and pests during its growth. Traditional prevention and control methods often focus on solving a single problem, such as using herbicides, fungicides or pesticides alone, which not only increases the cost of agricultural production, but also causes potential harm to the environment and human health, while affecting the quality and yield of wheat. Therefore, it is particularly important to develop a comprehensive method that can simultaneously remove weeds, prevent diseases and prevent pests. Therefore, we proposed a method for weeding and preventing diseases and pests in wheat fields to solve the above problems.

[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

[0051] Note:

[0052] Manual application of pesticides: walk slower if there is more grass, and walk faster if there is less grass.

[0053] Drone spraying: appropriately reduce the amount of pesticide used and relatively increase the amount of water used.

[0054] Fully automatic flying spraying: stay away from non-wheat crops such as vegetables and fruit trees.

[0055] It is prohibited to apply pesticides to yellow seedlings, weak wheat, diseased wheat, waterlogged wheat, and wheat with exposed roots.

[0056] The present invention organically combines weeding, disease prevention and insect control in wheat fields to form a complete set of new integrated technology for the prevention and control of wheat field diseases, insects and weeds. All the pesticides used are high-efficiency and low-toxic ingredients with novel complementary efficacy, reasonable ratios, cost savings and efficiency improvements, truly achieving prevention first, comprehensive prevention and control, one spray for multiple preventions, reducing environmental pollution, increasing wheat yield, improving wheat quality, increasing farmers' income and promoting sustainable agricultural development.

[0057] After 6 years of exploration, experimental practice and field application by the invention team, it was shown that the following phenomena did not occur in a short period of time when the herbicides, fungicides and insecticides of the present invention were mixed: antagonism, reaction, precipitation, bubbles, floating oil, stratification, discoloration, heating, reduced efficacy and the like.

[0058] The present invention can be applied to field practice to save more than 66% of labor time, and the wheat field only needs to spray 1-3 times less pesticide, which greatly improves the operation efficiency and saves labor cost.

[0059] The present invention can be applied to field practice to save more than 50% of the pesticide dosage, and the time for controlling diseases and insect pests in wheat fields can be advanced by 20-40 days compared with the traditional drug application time. At this time, the base number of wheat diseases and insect pests is small, the insects are few and the diseases are mild, and the leaf area is also small. A small amount of fungicide and insecticide pesticide can be used to control most diseases and insect pests in wheat fields, achieving twice the result with half the effort.
