Weed Management

Weed
Wheat is an important cereal crop. Here some generally weeds grown in field Anagallis arvensis (Krishananeel कृष्‍णनील), Argemone mexicana (Satyanashi सत्‍यानाशी), Asphodelus tenuifolius (Piazzi प्‍याजी), Avena ludoviciana (Jangli Jai जंगली जंई), Cannabis sativa (Bhang भांग), Carthamus oxycantha (Pohli पोहली), Chenopodium album (Bathu बथुआ), Cirsium arvense (Kateli कटैहली), Convolvulus arvensis (Hirankhuri हि‍रनखुरी), Corpus Didymus (Pitpapra पीतपापडा), Euphorbia jelioscopia (Dudhi दुधी), Fumaria parviflora (Gajri गाजरी), Lathyrus aphaca (Matri मटरी), Malva parviflora (Gogisag गोगीसाग), Medicago denticulata (Maina मैना), Melilotus alba (Metha मेथा), Phalaris minor (Mandushi/Gulidanda मंडूशी), Poa annua (Poa ghas पौघास), Polygonum plebejum (Raniphul रानीफूल), Polypogon monspeliensis (Lomar ghas लोमरघास), Rumex retroflex (Jangli palak जंगली पालक), Spergula arvensis (Bandhania वनधनि‍या), Vicia sativa (Chatri/Gegla गेला) are weeds which affect the production of crop and decrease the quality


Phalaris minor is one of the major weed of wheat crops in the rice-wheat cropping system. Sometimes its population is too high (2000-3000 plants/ m2) those farmers are forced to harvest the wheat crop as fodder. Isoproturon (Arelon) was recommended for the control of Phalaris minor in the 1980s. It remained effective for almost a decade. However, sole dependence on this herbicide resulted in the development of resistance to Isoproturon in Phalaris minor.

In zero tillage fields, the intensity of Rumex and Malwa parviflora is increasing and may become a problem in the coming years. Therefore, we must remain vigilant regarding the weed flora shift due to changes in tillage practices.
Weed Management Practices in Wheat
Various practices of weed management can be grouped into three broad categories namely cultural and preventive; physical or mechanical; and chemical weed control.
Mechanical Control
It involves the removal of weeds by various tools & implements including hand weeding & pulling. It is not feasible where weeds resemble morphologically to crop ego P. minor & Avena ludoviciana before flowering in wheat. Also, mechanical weed control becomes difficult in broadcast sown wheat. However, mechanical control can be practiced effectively when wheat is sown on FIRBS as this system facilitates tractor-mounted implements usage.

Don'ts
  1. Do not use Sulfosulfuran in a mixed cropping system of wheat and mustard or other crops.
  2. Never apply these post-emergence herbicides by mixing with sand, urea or soil.
  3. Do not mix Clodinafop and Fenoxaprop with 2,4-D
