Q: The dry direct rice I planted was closed before the seedlings and was removed half a month ago with the addition of Han Qiuhao Jia Pao Dan. Now, a lot of grass grows in the fields. Excuse me: How can I eliminate it again?
Answer: The early weeding effect is not ideal, and more weedy plots can be replaced at the 3 leaf stage of seedlings. Seedlings are drained at the 3rd leaf stage, and the next day after draining, Shenmu (50% quinacridone wettable powder) 50g plus 10% bensulfuron-methyl wettable powder 20g, add water 30kg uniform spray Or use Oryzae (25% Penoxsulam Sulfate Suspension) 60-80 ml or Rice Nongyro (32% Benzodichlore WP) 60g per acre, add 30 kg of water evenly. There are thousands of gold fields, in Qianjin 2~3 leaf stage with a thousand gold per acre (10% cyanomethoxime EC) 50 ~ 70 ml, add 30 kg of water evenly spray. Daughters must not be used in combination with agents that control broad-leaved weeds. Orchards with broad-leaved weeds can use 40 to 60 ml of rice seed per mu, or use 10% bensulfuron-methyl per mu for a week after daughters are applied. 20 grams of powder, add water, spray 30 kg. Rice fields that have been treated with omelocrazol or prepared for paclobutrazol cannot be applied with chloroquine-containing herbicides. Be careful not to re-spray and arbitrarily increase the amount of medication.
Respiratory Protection
is a device designed to protect the wearer from inhaling particulate
matter, including airborne microorganisms, fumes, vapours and gases.
There are two main categories: the air-purifying respirator which forces
contaminated air through a filtering element, and the air-supplied
respirator in which an alternate supply of fresh air is delivered.
Within each category, different techniques are employed to reduce or
eliminate noxious airborne contaminants.
Respirators
range from relatively inexpensive single-use, disposable face masks to
more robust reusable models with replaceable cartridges.
They are also sometimes referred to as a dust mask or a gas mask.
