Stem and leaf treatment involves applying herbicide solutions evenly to the stems and leaves of emerging weeds. According to the China Pesticide Network, the selectivity of these herbicides mainly relies on differences in the morphological structure and physiological or biochemical characteristics of plants. This allows for effective weed control while protecting the crop seedlings. Some post-emergence herbicides, such as aryloxyphenoxypropionic acid (AOA) herbicides, are significantly affected by soil moisture levels. During dry conditions, their effectiveness can be greatly reduced. Therefore, timing is crucial—applying herbicides at the right stage ensures optimal results.
Post-emergence stem and leaf treatments typically use selective herbicides like bensulfuron-methyl, which are widely used in rice fields to manage weeds growing between and around rice seedlings. These herbicides target specific weed species without harming the crops. However, careful selection and application are essential for success.
The China Pesticide Network reminds users that when choosing herbicides for stem and leaf treatment, three key factors should be considered. First, it's important to apply the herbicide at the right time. For example, in rice fields, it’s best to apply after transplanting when the crop is still green. For soybeans, the 2-3 leaf stage is ideal, and for corn, the 3-4 leaf stage is most effective. Second, the type of weed present in the field should guide the choice of herbicide. Different weeds may require different formulations for effective control. Third, users should be aware of the residual effects of herbicides. Some, like broadleaf herbicides used in rapeseed fields (such as sulfosulfuron), can remain active in the soil for several months or even years. This long-lasting effect can cause serious damage to subsequent crops if not managed properly.
By following these guidelines, farmers can maximize the benefits of stem and leaf herbicide treatments while minimizing risks to future planting cycles. Always refer to local agricultural extension services for recommendations tailored to your specific region and crop type.
Cutting Wheel
Diamond cutting piece is a widely used in stone, concrete, precast board, new and old roads, ceramics and other hard brittle materials processing.
Diamond cutting pieces are mainly composed of two parts; Matrix and cutter head,
The matrix is the main support part of the bonding tool head, and the tool head is the cutting part in the process of use.
The tool head will be constantly consumed in use, while the matrix will not. The reason why the tool head can play a cutting role is that it contains diamond. Diamond, as the hardest material at present, cuts the processed object by friction in the tool head, while diamond particles are wrapped in metal inside the tool head.
According to the shape of the knife head, there are different effects:
1. Continuous edge Saw Blade: continuous saw diamond cutting blade, generally made by sintering method, water must be added when cutting to ensure the cutting effect, and the type of gap will be cut by laser.
2, knife head cutting piece: serrated disconnect, cutting speed, suitable for dry and wet cutting methods.
3, corrugated cutting piece: combined with the advantages of the first 1, 2, serrated continuous corrugated uniform convex and concave, improve the cutting speed, increase the service life.
