Simazine,[link widoczny dla zalogowanych], Gramoxone, Roundup Ready herbicide concentration of economic use

Thus, over a period of time, some weeds such as barnyard grass, wheatgrass can be resurrected, but growing significantly decreased. Gramoxone major damage to leaf green cable, so use special care not to spray when foliage or fruit to the fruit surface. 3. Glyphosate is a suction-type off naturally within the leaf treatment agent, generally a 6 to 8 leaf weed use can help the absorption of about 6 days after the effective spraying, the killing effect of both above and below ground, so for the exception of the grass. Broad-spectrum herbicide glyphosate, weeds are almost all valid, but some broad-leaved weeds in deep roots, such as wild Ai Qing Ma and so is slightly stronger resistance. The experiment compared to the main control early weed simazine, Gramoxone. The main control weeds in Roundup Ready late. Larger weeds, the stronger the resistance. Therefore, herbicides complement each other on the use of better fitness. They are the best use of economic concentration: Simazine 150 - 200g / mu, glyphosate 200ml / mu Gramoxone 100 - l5Oml / mu. Not only the effect of chemical weeding,[link widoczny dla zalogowanych], and weeding less labor than other methods, and low cost. Costing in the table below. Different ways of handling the amount of weed costing the frequency of use unit cost (yuan / mu) simazine l50g / acre 7 yuan / kg1 times where work 1 drug 4.2 g wu track 15o ~ 200m�� / mu l5 per / kgl3.0 Roundup Ready 220m�� / mu�� 2 yuan / kgl2.4 artificial l acres / man-days 25 yuan / T6l50 on the door mechanical / 5 yuan / mu 3l5.0 film 1kg / mu l1 yuan / kg1l1 (ok) General / / 1 1 King Machinery 7.0I King King of artificial drugs Note: the average height of weed control is always 20cm. The next case of the right 33 - Grass should be noted that use of herbicides spine asked condemnation: �� Sometimes a herbicide in different years in different locations or the effect of using different, which soil properties, weed status, spraying time, spraying quality and the climatic conditions after application so you must know before spraying herbicide on the nature and application of technologies such as Roundup Ready within 12 hours after spraying rain will become invalid; simazine in the long-term drought conditions or soil poor water play when the pharmacy; some herbicides such as storage of not more than two years, only the correct selection and application to be effective. @ North Orchard prevention focus is a year old late spring weeds (such as crabgrass, barnyardgrass, cocklebur, Plantago, shepherd's purse, chicken children grass. Brome, iron, amaranth, purslane, hot dad, etc.), these weeds occurring on a large period of 5 to 8 months, so this period is the focus of prevention and control; into September and then after the herbicides do not control. �� weed control than a single integrated platform approach is more reasonable, as in labor or weeds more than adequate, it can manual weeding, or great harm, but some agents are not effective weed supplemented by artificial exception of the grass; use of weed agent before the early spring with tillage weed eradication, chemical control can increase the effect; especially for a orchard intercropping, the use of cultivation, weed is still very necessary. In addition, some of the edge of orchards scattered lots, should be noted that artificial elimination of weeds, in order to avoid increasing the base of the weeds in the orchard. �� most types of herbicides are effective low toxicity, according to our experience, stems and leaves of herbicide spray to fruit trees as long as no new organs (bud, bud, flower, leaf,[link widoczny dla zalogowanych], shoot), the injury would not have happened; soil spraying herbicide directly to the ground, the liquid does not touch the tree, the general injury does not occur, but when weeding their mobility Yan large, easy to penetrate the soil, the use of too much concentration or amount of liquid after spraying under Rain or irrigation immediately, may cause injury of fruit trees is a deep root crops. Produce injury is often the young trees, so long as attention when spraying can be avoided. Matilda Mu Xi Zhang orchard herbicide wind Fangshan Fangshan District, Beijing Forestry Forest Technology Extension Station Beijing Fangshan Village has Huinan 530 acres of orchards, the implementation of professional management of the entire park. Management of the orchard area of 125 mu per capita. Orchard weed species: crabgrass, cocklebur, grass law, boron bindweed, thistle, thorn and grass more than l0. Chemical weed control in 1989 tests. Jing herbicide use is: Gramoxone (20%), glyphosate (10%), and Arrest net (20%), the amount per acre were: 200g, 4O0g, 100g, 25kg water in a spray in early July . Using knapsack sprayer, spray the neck to install special duckbill, select fine calm weather, in the morning dew evaporates spraying paternity, the results (see table below) glyphosate. Take the best fishing net weeding,[link widoczny dla zalogowanych], weeding period about 45 days. Spraying of herbicides in early July, to be recycled after the autumn when the weeds, growing weaker, no longer than chemical weed control compared with manual weeding, chemical weeding investment 4.7 yuan per mu, manual weeding than the 76.9% saving investment and improve efficiency 30 times.
