Last Updated: 2024/11/08, 1. Weed control before sprouting after sowing, before sprouting of lilies after sowing, mu (1 mu = 1 hectare, the same below) with 33% herbicide oil 100-150 ml plus water 50-75 kg evenly sprayed on the ground, the effect period can reach 50 days; with 48% Dele'an EC 200 ml plus water 50-75 kg evenly sprayed ground, the effect period can reach about 30 days. In addition, 50% herbicide No. 1 wet powder 120-150 grams per mu, or 30% poisonous chlor EC 500 ml, or 60%

1. Weed control before sprouting after sowing

After sowing, before sprouting, the mu (1 mu = 1 hectare, the same below) is sprayed evenly with 33% Weatong floating oil 100-150 ml plus 50-75 kg water, and the effect lasts for 50 days; with 48% Dele'an EC 200 ml plus 50-75 kg water, the effect can be evenly sprayed for about 30 days. In addition, 50% herbicide No. 1 wet powder 120-150 g per mu, or 30% chlorachlor EC 500 ml, or 60% acetachlor EC 300-400 ml, or 15% isoprolong wettable powder 200-250 g per mu, or 50% herbicide No. 1 wettable powder 100 grams plus 50% prometryne wettable powder 50 grams Or 30 grams of poisonous chlor EC 300 ml plus 25% herbicide EC 120-150 grams (any of the above agents can be) add 50-75 kg of water to spray the ground soil evenly before emergence after sowing lily seeds.

II. Weed control at seedling stage

Lily seedling stage is long, in order to prevent newborn weeds from being unearthed, 33% trifluralin EC 100150ml or 48% trifluralin EC 100150ml can be used per mu (trifluralin is afraid of light, to prevent photolysis, shallow hoe should be about 1cm after spraying, make it mixed with soil to better play the role of weeding) or 48% trimethoprim EC 200ml, or 25g herbicide wettable powder 500g-1500 g Or 100 grams of 50% Liguron wettable powder, or 150 grams of 50% prometryne wettable powder, or 750 grams of 25% chlorpromazine wettable powder (either of the above agents) add 50-75 kg of water and evenly spray the surface soil at the lily seedling stage and bulb stage for 2-3 times, all kinds of weeds can be effectively controlled. If the lily does not use herbicides at the seedling stage, when the lily suffers from grass damage after emergence, it can be sprayed on weeds with 50% Riguron wettable powder 75-100g per mu, or 1000 ml of herbicide oil, or 20% paraquat 100g or 20% paraquat (either of the above chemicals) for directional stem and leaf spray.

The above-mentioned methods can effectively control many kinds of weeds that harm the normal growth of lily, such as dogtail grass, barnyard grass, horse tang, wild amaranth, gray vegetable and so on.
