In the case of continuous rainy weather after sowing of direct-seeded rice, there are often cases of water accumulation in the field, resulting in the inability to apply herbicides in a timely manner, or the field where herbicides are applied is washed away by rain, and the soil layer is damaged and affects control efficiency. .
In order to ensure the weeding effect, the following remedial measures may be taken after the weather improves for live rice fields that are continuously raining after being sown. (1) For direct-seeded rice fields that have not been removed after sowing for more than 4 days, if the weeds have not yet occurred or the grass age is very small, it is possible to use the 20% besamochlor WP as the soil sealing treatment. The conventional dosage of this medicine is 120 grams per mu. Considering that the herbicidal effect of delayed drug use may decrease, the dosage should be appropriately increased, and 180-240 grams per mu can be used. As long as the field does not contain water after the drug, there is no adverse effect on rice growth. (2) Closed herbicides are applied 1 to 2 days before the rain, but due to heavy rainfall, the fields under heavy rain washed away and the drug layer is destroyed, it is necessary to supplement 20% benzacetam in Shirayao after the rain. Wettable powder, 120-150 grams per mu. (3) timely treatment of valerian. The use of 20% benzacetazone WP in the wild rice will be delayed, and the control effect on grasses such as barnyardgrass will decrease, but the control effect on broadleaf grasses will be minimal. In the field of deferred drug use, as long as the seedlings are in the 3-leaf stage, 60% of chloroquine WP or 25g of wild rice and 10% of chlorfluazuron EC may be sprayed with wild water, usually Effectively control weed damage.
