Fluroxypyr is an herbicide in the class of synthetic auxins. It is used to control broadleaf weeds and woody brush. It is formulated as the 1-methylheptyl ester (fluroxypyr-MHE)
Characteristic
1. Control cleavers, stem volume Polygonum, Portulaca oleracea, Solanum nigrum, chickweed, vetches, field bindweed, Itachi flap flower, lapathifolium, willow thorn Polygonum, anti retroflexus, Commelina communis, Elsholtzia, Thlaspi arvense, vetch, sowing Descurainia sophia L. and small bindweed, etc all kinds of broad-leaved weeds, ineffective in Gramineae and Cyperaceae weeds.
2 to crop safety, in drug resistance, so that it can be combined with the conjugate of the conjugate and lose the toxicity.
3 in soil, easy degradation, short half-life, not after crop damage.
Use method
(1) for control of weeds in wheat field: in the winter after returning green stage or tiller peak stage to jointing stage, spring wheat 3-5 leaf stage, broadleaf weed leaves 2-4 period per acre with 20% make it long EC ml 50-66.7, of water spray.
(2) weeds in corn field: in maize seedlings after 6 leaf stage before weeds 2-5 leaf stage, with per mu with 20% make it long EC ml 50-66.7, of water spray; weed control field bindweed, Convolvulaceae, purslane refractory per acre with 20% make it long EC ml 66.7-100.
(3) control of grape, orchards, farmland and rice ridge weeds: in 2 to 5 leaf stage of weeds, with per mu with 20% make it long EC 75-150 ml, the spray of water. Control of rice ridge hollow lotus seed food per acre with 20% make it long EC 50 ml, 20% or make it long EC 20 ml and 41% Mn Ba water 200 ml mixed or 20% make it long EC 30 ml and 41% Mn Ba water 150 ml mixed. Control such as Scirpus triqueter, Polygonum chinense, Rubus parvifolius, Commelina communis, To etc. refractory weeds, with per mu with 20% make it long EC 80-100 ml and 41% Mn Ba water 150 ml mixed.
Mixture
Starane with other herbicides, can expand weed killing spectrum, reduce the cost. In the fields of wheat per mu with 20% make it long EC 30-40 ml add drop of 72%2,4- butylate 35 ml or 20% dimethyl tetrachloro water 150 ml can effectively control the mother-in-law Na, Euphorbia helioscopia, shepherd's purse, Cardamine, Rui mustard, Chenopodium album, horsetail, endive, field bindweed, Scirpus triqueter, and piemarker as weeds from the per mu. The 20% make it long EC ml 50-66.7 6.9% fenoxaprop-p-ethyl EW plus. Ml can effectively control of wild oats, Mai Niang, hard grass, Polypogon fugax, barnyard grass, crabgrass, thousands of gold gramineous weeds.
Notice
The 1 application, the nonionic surfactant added amount of spraying 0.2% to make it long in the liquid, can improve the efficacy.
2. In the low temperature, hourly wind speed of medicament spraying, air relative humidity of less than 65%, temperature is higher than 28 degrees, wind speed more than 4 m / s to stop spraying.
3. In the orchard spraying, avoid will make it long liquid spray directly to the fruit, avoid in tea and banana plantations and adjacent land use to make it long.
4 spray to make it a spray, should be thoroughly cleaned before it can be used for the broad-leaved crops field spraying other pesticides.
