How to Correctly Remove Wheat Field Weeds
To improve control of weeds in wheat fields, we must correctly choose safe and reliable herbicides, and “prescribe the right medicines†to prevent and cure them in due course. Here we describe the weed removal methods for two types of wheat fields. 1. The main weeds of the wheat fields in the rice field in Putian are: See Aunt, Swine Frog, Flycatcher, Veronica and other species. Generally, weeds are gradually exhumed 7 to 10 days after sowing, and sprouting stops at the end of December. This type of weed had a high seedling density in the past year, and had a small grass age. From the 3rd leaf to the tillering stage of wheat seedlings, it was possible to select a good weather with a daily average temperature of 10°C or above, using 48% herbicidal admixture 12.5 ml/mu plus 13% 2 A 4 chlorine water agent 150 ml; if you look at Alabama more fields can also use 25% chlorotoluron WP 100 g / acre plus 13% 2 A 4 chlorine water agent 150 ml, watered 30 kg stem leaf spray . Note that the formula is disabled at the end of the tillering period and until the beginning of the jointing stage. 2. The main weeds in the field of wheat in Soybean Meal are: Poria cocos, Laverna, Dachao, Amaranthus, Amaranthus, Porcariae, yak seedlings (sunflower), Ze-lacquer, and stems. The type of weeds in this type of field was less preemerged, with more emergence after the year and higher density. From late February to early March, wheat seedlings 3 leaves to the beginning of jointing, with 75% broad-leaved net or broadleaf dry suspension 1.2~1.5 g/mu, 20% can also be used to make it 40~50 ml / Acre; If you look at Acacia's many plots, you can add 6.9% per acre water emulsion 50 ml, both watered 30 kg stem leaf spray. Hummer should be used with caution in the middle and later stages of the jointing of wheat seedlings to prevent phytotoxicity. The above methods have the effect of controlling the weeds in wheat fields by 90 to 95%, which is safe for wheat fields.
