Can glyphosate kill grass picked home.
Glyphosate, a non-selective, non-residual inactivating herbicide, is very effective on perennial rooted weeds and is widely used in rubber, mulberry, tea, orchards and sugarcane fields. It mainly inhibits the enolpyruvyl mangiferin phosphate synthase in plants, thus inhibiting the conversion of mangiferin to phenylalanine, tyrosine and tryptophan, which interferes with protein synthesis and leads to plant death. Glyphosate is absorbed through the stem and leaves and then conducted to all parts of the plant, and can protect against more than 40 families of plants, including monocotyledons and dicotyledons, annuals and perennials, herbs and shrubs. Glyphosate quickly combines with metal ions such as iron and aluminum after entering the soil and becomes inactive.
It was initially used in rubber plantations to prevent thatch and other weeds, which can make rubber trees cut rubber 1 year earlier and increase the yield of old rubber trees. Now it is gradually promoted in forestry, orchard, mulberry garden, tea garden, rice and wheat, rice and oilseed rape crop rotation. Various weeds have different sensitivity to glyphosate, and thus the dosage is also different. For example, for annual weeds such as barnyard grass, dogweed, look-at-meadow grass, oxalis, Matang, and pork-bane, the dosage of glyphosate is 6 to 10.5 g/100 square meters in terms of the active ingredient. The dosage of the active ingredient is 11.4 to 15 g/100 square meters for plantain, small fleabane, plantain, and so on. For white fescue, sclerotium, reed, etc., 18 to 30g/100 square meters, generally 3 to 4.5kg of water, to the weed stems and leaves uniform directional spraying. Generally, broad-leaved weeds in the early budding or flowering stage, grass in the late nodulation or early tasseling 20 to 30 kilograms of water per mu dosage spray. Plants that have been cut off the stems and leaves should wait until the weed propogates to have enough new leaves before applying the drug. When preventing perennial weeds, a single dose divided into two times, 5 days between applications can improve the effectiveness of prevention.
Prevention of apple orchards, peach orchards, vineyards, pear orchards, tea gardens, mulberry gardens and farmland recreational land weeds, barnyard dogweed, look at the maidenhair, oxalis, Matang, araucaria, quinoa, traditional witch hazel, pig charcoal and other annual weeds.
Glyphosate has a herbicidal effect only after contacting green tissue. Because of the different responsiveness of various weeds to glyphosate, the dosage is also different.
1. Orchards, mulberry gardens and other weed control Use 10% water 0.5 to 1 kilogram per mu for preventing 1-year-old weeds, and use 10% water 1 to 1.5 kilogram per mu for preventing perennial weeds. Add 20 to 30 kilograms of water to the weed stems and leaves for targeted spraying.
2. Farmland weed control Farmland stubble before sowing to prevent and eliminate the field has grown weeds, the amount of drugs can be referred to the orchard weed control. Cotton growing season medication, need to use hooded spray directed spray. Use 10% water 0.5 to 0.75 kilograms per mu, 20 to 30 kilograms of water.
3. Recreational land, field, roadside weeding In the weed 4 to 6 leaf period, per mu with 10% water 0.5 to 1 kg, plus diesel 100 ml, 20 to 30 kg of water, on the weed spray.
4. For some malignant weeds, such as fragrant reed, etc., can be added in accordance with 200 grams per mu of land additives, weed control effect is good.
After using glyphosate at least one week to ten days interval to plant corn and other large seed crops, if you want to plant vegetables and other small seed crops, at least one month, the residual period can be seen in general, and even if the amount of use is too large, a year is difficult to degrade.
Glyphosate is used in grapes, kiwi, peach trees and other shallow root crops, not watering or rainfall is okay, until the rainfall or watering, there will be obvious symptoms of poisoning on the leaves, the fruit will basically stop growing, even if you can continue to grow, there will be deformed fruit. If it is used in the date tree and other string roots to grow saplings on the fruit trees, the drug is certain to appear undoubtedly.
