معرفی علف کش کلومازون (CLOMAZONE 48%EC) به عنوان یک علف کش امید بخش بمنظور کنترل پیش رویشی علف های هرز در زراعت نیشکر استان خوزستان.

Sugarcane is a plant that grows for a long time, especially at the beginning of growth (6 to 8 months in newly cultivated fields) and has a slow growth, and these distances between the rows are very large (160 cm), and weed control faces a lot of challenges. slow On the other hand, most of the herbicides in this agriculture belong to the photosynthesis inhibitor II family, and resistance to this family has been observed in most of the narrow-leaved and some broad-leaved weeds. In order to check the effectiveness of clomazone herbicide to control the growth of weeds in sugarcane fields, an experiment was conducted in the crop years 1401 to 1403 in three consecutive years in September (during the cultivation of Plant farms) and also in April and April (spring) in the fields of the company. And Sanat Karon was implemented in the form of t-test experiments. The experimental treatments included: application of EPTC herbicide (Eradicane) 5 liters per hectare and pre-emergence application of clomazone at the amount of 1 liter per hectare by two methods of Herbigation and pre-emergence spraying after the first water. The results showed that clomazone herbicide in the amount of 1 liter per hectare was as effective as Eradicane 5 liters per hectare in both methods of Herbigation and pre-emergent spraying. In addition, the control period of Eradicane herbicide 5 liters lasted for one month and in the treatment with clomazone, it lasted for three months. The effects of clomazone on sugarcane cultivation were not observed in the irrigation method, but in the pre-emergence spraying method after the first water in the spring due to the heat of the air and the wind blowing of the herbicide. On sugarcane leaves, sugarcane leaves showed a little chlorosis (about 7% in the EWRS observational evaluation, grade 3 and the description of the characteristic is slightly severe and unstable), which was gradually resolved after two weeks. Therefore, clomazone herbicide is a promising herbicide for control Weeds of sugarcane fields are introduced.
