1, plasticine: it can not only delay the growth and senescence of plant vegetative body, but also delay its flowering, fruiting and maturity. Plasticine can be absorbed by seeds, roots and leaves, and its distribution in plants has no polarity, and its transportation direction mainly depends on the growth and development stage of plants when used.
2. Alternanthera philoxeroides: suitable for controlling all kinds of annual and perennial broadleaf malignant weeds. Sensitive weeds come into contact with Alternanthera philoxeroides, and the plants are deformed and twisted, and finally stop growing. It is forbidden to use water peanuts in and around hybrid rice Taneda. After using water peanuts, if it rains within 8 hours, it needs to be sprayed again.
3. Cloflupiroxic acid: Cloflupiroxic acid is a kind of systemic and conductive post-seedling herbicide, which is quickly absorbed by plants after taking it, causing sensitive plants to react with typical hormonal herbicides, causing plants to deform, distort and eventually die.
4. Glyphosate: Glyphosate is a non-selective and residue-free herbicide, which is very effective for perennial rooted weeds and is widely used in rubber, mulberry, tea, orchards and sugarcane fields. It mainly inhibits enolacetone shikonin phosphate synthase in plants.
5. Ammonium sulfate: Ammonium sulfate can promote the absorption of glyphosate by Alternanthera philoxeroides and its accumulation in underground roots, and the application of 250 ml+150 ml twice can achieve excellent results for the underground parts of Alternanthera philoxeroides in orchards.
