For which, where farm laborers are easily available at cheap rates, weeding should be done by hand after sowing and for 30 days. But where there is a shortage of labor, for control of chemical weeds, pendimethalin (2.5 liters) is applied at the rate of 1.0 kg / ha. According to the active ingredient or fluchloralin (2.0 liters) 0.300 kg. The active ingredient or oxidiazone (2.0 liters) is 1.0 kg. According to the active ingredient, dissolve in 500 liters of water and immediately after sowing, before sowing, i.e. pre. Emergency spraying can lead to effective weed control.
Garlic
Since garlic is a shallow rooted crop as well as short sown, it is very important to keep it free from weeds during the first two months.

According to the active ingredient or oxytocin orofen (1.0 liter) drug 0.50 kg / ha. According to the active ingredient dissolved in 500 liters of water, the next day after sowing the crop i.e. pre. Weeding by hand once in 30 days after sowing along with spraying as emergency is effective control of weeds.
Onion
Since onion is cultivated at a very short distance, it is not possible to intercrop it. So it is very important not to keep the onion crop free from weeds during the first two to two and a half months. If the onion crop is not kept free from weeds during this period, the onion production will decrease by 50 to 6 per cent. Therefore, instead of using chemical pesticides where cheap and adequate labor can be obtained in time, weeding should be done by hand once or twice in 20 and 30 days after replanting. But where weeding is not possible by hand only, for integrated weed control, a drug called fluchloralin (2.0 liters) or pendimethalin (2.0 liters) per hectare 0.900 kg. According to the active ingredient or oxidiazone (2.0 liter) drug 0.950 kg / ha.
