How is the non-selective herbicide paraquat used? What is the dosage? We ask netizens to help explain.Paraquat is a contact non-selective herbicide that can be used for weed control in orchards, mulberry fields, lawns and ditches. Zhongdi Network has compiled the usage methods, listed below for netizens' reference.
How paraquat is used in orchards and mulberry fields:
Because paraquat has no effect on non-green cortical tissue and is adsorbed and deactivated after the chemical contacts the soil, it can be used for directed spray weeding in orchards and mulberry fields. Even with repeated application, it does not affect the growth of the plant root system.
How paraquat is used on lawns:
Because paraquat only kills the green above-ground parts and is harmless to the underground parts of plants, it can be used for lawn renewal and for controlling warm-season lawn weeds in winter.
1. Use for lawn renewal: Applying paraquat during the growing period of perennial lawns can kill the above-ground parts of the lawn grass and promote the growth of new stems and leaves.
2. Use for controlling warm-season lawn weeds in winter: In winter, the above-ground parts of perennial warm-season lawn grasses such as Manila grass and bermudagrass dry up, while at this time the seeds of some weeds that grow in autumn and winter germinate and grow. Applying paraquat can effectively control these weeds and ensure the safety of the lawn grass.
How paraquat is used in ditches:
Ditches are often overgrown with weeds, which affects irrigation and drainage. Spraying paraquat during the period of vigorous weed growth can kill the above-ground parts of the weeds, achieving the effect of clearing and dredging the ditch system, while preserving the weed root system to prevent the soil on both sides of the ditch from collapsing.
Paraquat usage method and dosage:
Generally, 200 milliliters of 20% paraquat per mu is mixed with 50 kilograms of water for spraying. Choose a windless sunny day for spraying to prevent the spray liquid from drifting onto other crops. After spraying, the sprayer must be repeatedly cleaned.
