WEEDS are the plants. They grow in the fields where they compete with crops for water,
soil nutrients, light and space and thus reduce crop yields. Weedicides increases
their yields and ensures the efficient use of irrigation, fertilizers and plant
protection measures, such as the spraying of insecticides and fungicides.
To manage the weeds in direct seeded rice, four weedicides were tested and
compared their efficacy with hand weeding.
Ternary Weedicide Composition:
The weedicide composition is a ternary weedicide composition consisting of nicosulfuron,
atrazine and bromoxynil octanoate which serve as active ingredients, wherein the
weight ratio of the nicosulfuron, the atrazine and the bromoxynil.
Analyze and Blending:
The preparation method of the composition comprises the following steps of melting
the metered bromoxynil octanoate, throwing the melted bromoxynil octanoate into
a ball mill, adding unprocessed pesticides of the nicosulfuron and the atrazine,
performing ball-milling for 2 to 3 hours, adding the mixture into a sand
grinder to grind for 3 to 4 hours, pumping the mixture into a blending tank
of a finished product, sampling to analyze and blending.
Prevention and Removal of Weeds:
The composition is applicable to prevention and removal of weeds in fields,
particularly to the prevention and removal of weeds in a maize field. The weedicide
composition of the invention can take the effect of removing seeds in very short
time and has good seed removing effect, so that the using amount of weedicides
can be reduced.
Types of Weedicide:
Two types of weedicide generally we find in the market. One is herbal or
botanical weedicide and another is chemical weedicide.
What are the examples of Weedicides:
Weeds are unwanted plants growing among wanted crops and compete with
crop plants for sunlight, nutrients, water, etc. They will not show any
effect on crop plants. Two popularly used weedicides are 2,4-d ethylester,
neem extract, glyphosote etc.
What are weeds and Weedicides:
Weeds are the unwanted plants which grow along the main plants and compete
with water, minerals, nutrients etc. Examples :- Xanthium, fieldbindweed,
Quack grass etc. Weedicides are the chemicals which help in killing the weeds
which acts like a manure.
What is the right time to spray Weedicides:
The Right time of spraying Weedicide is after 32 - 40 days of Sowing .
This time can be Extended to one more week . But not more than 40 days
of sowing because the weeds had already cause damage to the crop.
Which instrument is used for spraying Weedicides:
Sprayer is an instrument that is used for spraying weedicides.
What are the harmful effect of weeds:
They interfere in harvesting. They compete with crop plants for water,
nutrients, space and light. They affect plant growth. Presence of weeds
increases the cost of agriculture and hinders the progress of work.
Why Weeding is necessary:
1)Weeds compete with crop plant for water, sunlight, nutrients, space and
hence affect plant growth. 2)Some weeds are poisonous for human and animals
whereas some weeds interfere in harvesting.
How do you apply Weedicides:
I recommend the farmers to use flood jet and flat fan nozzles for uniform spray of
weedicies on the weeds and never use cone type nozzles for spraying weedicides
to get good results, spray should be done in a straight strip, the nozzle should
not be moved away from the strip and it should be kept 40 to 50 cm above.
How do you kill weeds without killing grass:
How to Get Rid of Weeds Once and For All — Without Ruining Your Lawn.
Apply Corn Gluten Meal.
Lay Down Mulch.
Pull Weeds by Hand.
Use the Right Amount of Fertilizer.
Water Your Lawn Deeply.
Mow Your Lawn High.
Use Weed-Specific Herbicides.
What are the most common lawn weeds:
Learn more about some common lawn weeds and how to deal with them. Crabgrass,
Dandelions, Quackgrass, Nut Sedge, Moss, Bindweed, White Clover, Cinquefoil.
How do you stop weeds from growing:
Mulch Your Beds. An effective and natural option to prevent weeds from taking
over your garden is through the use of mulch. Apply a thick layer of organic
mulch approximately 2 inches deep in the garden area – take care to avoid the
base of individual plants and shrubs.
What are two reasons for weeding:
Weeding is an important control method practiced in many crops. The removal of
weeds is useful because these unwanted plants compete with the crop for space,
water and nutrients. Weeding also helps to loosen the soil. Water can
infiltrate more rapidly and roots of the cultivated plants can develop
in a better way.
Are Weedicides poisonous:
Weedicides Containing Glyphosate, Used In Farming, Can Cause Cancer; Recent Study
Confirms. In a recent study that has come up, it has been proved that rampant
use of glyphosate has carcinogenic impacts, thus raising severe safety concerns.
How is weeding done manually:
Weeding is done manually by using khurpi and by using mechanical machines.
Weeds are also controlled by using some chemical substances like 2, 4-D.
These chemicals are called weedicides and are used to kill and destroy the weeds.
What is herbicide formulation:
Typically, pure herbicide molecules are of limited value to the end user.
To give them practical value and usable, most herbicides are combined with
appropriate solvents or surfactants to form a product called a formulation.
The formulation is a liquid and consists of the active ingredient and additives.
What are the three main types of use for herbicides:
What Are the Different Types of Herbicides.
Herbicide Types. Herbicides can be classified in several ways: effect, selectivity,
persistence, application and action.
Effect. Pre-emergent herbicides: Work as they interfere with seed germination.
Selectivity, Persistence, Application, Action, Glyphosate Herbicide, References.
