Hello Everyone. I am @shiftitamanna

My friend's vegetable garden
Along with the improvement of everything in the present developed world, there is also a lot of improvement in agriculture in the major agricultural countries. Earlier people used plow for agricultural work but nowadays people use tractor instead of plow to cultivate land. In addition, the use of various pesticides for the production of different varieties of crops has increased, which is now known as the shadow of advanced technology. We are constantly being introduced to improved varieties of crops to improve such farming that we can carry forward. Today's topic is pest and pest control which is very important for agriculture work and now I am presenting my homework on these topics.
When I visited the crop field I found most of the time the presence of rats and some other insects in the crop field which are harmful to the crop. I had originally visited the paddy field long ago because my uncle had accumulated paddy and I had gone there to see large rats digging in the soil which caused great damage to the crops. Basically, these rodents cut the roots of the crop plants from below the ground, causing damage to both the plant and the crop.
I was able to detect that these are harmful kits to crops. Because I have studied about these pests before and know that they are very harmful to crops. There are some insects that do not breed on crop leaves and eat the crop leaves. This prevents the crop from making its own food and causes the palm tree to wither and die. On the other hand, rats enter the crop fields and make large holes and then feed themselves by eating the roots of the crops, causing many crop plants to die. Annual surveys show that the amount of damage caused by all these pests and insects to the crop is combined.
Pests can be kept away by mechanical, chemical and biological methods in agriculture. In this case, good soil tillage prior to seeding reduces the pest burden and crop rotation helps reduce the formation of a particular pest species. I would also like to discuss some other ways by which pests can be kept away from crops.
Biological Control: This method is useful for pest control which uses predatory insects, parasitic wasps, ladybugs and nematodes to target and reduce pest populations. By doing so, they act as natural predators, feed on insects or parasitize, thereby controlling the population of these pests.
Cultural Practices: Cultural practices can reduce pest problems. These practices include maintaining optimal plant health through proper sanitation, weed management, proper irrigation, nutrition and pruning. Healthy plants act as pest and disease deterrents so pests fail to thrive here.
Genetic Resistance: Planting crop varieties bred for pest resistance that can provide natural protection against various pests. These varieties have genetic traits that make them less susceptible to specific pests and thus do not require chemical intervention.
Chemical method: Another way to get rid of pests from crop land is chemical pest control. In this process using different chemicals and substances harmful to insects. Chemicals that are harmful to pests will attract pests but when the pests come in contact with these chemicals, the pests and bacteria that are harmful to the crop will be eliminated. However, in this case, the crop also suffers some damage and poison is created in the crop.
Pheromone trap: It is a biochemical substance produced naturally by female insects of a species to attract male insects of the same species for breeding. The male insect is attracted by the smell of sex pheromone to mate with the female insect and falls into the trap and dies, which is known as magic trap to farmers.
Pheromone trap making rules: Pheromone traps usually require three ingredients and the ingredients are: pheromone bait, a trap and 1-2 poles to set up the trap. 22 cm in this trap. A long rectangular or round plastic container is used. 3-4 cm below the beam. Soapy water should be kept. Then 2-3 cm of water. The bait should be hung above.

Talking about the application of fertilizers I would say that all vegetables including paddy like sweet pumpkin, gourd, radish, turnip, brinjal etc. use organic chemical fertilizers even less. In particular, there is no need to use organic chemical fertilizers for the cultivation of Puishak. Basically, the main enemies of rice, wheat, corn are various pests, insects and weeds. Various pests and insects damage the leaves along with the root parts of the plant. On the other hand, weeds absorb the nutrients needed by plants from the soil, so the plant may die without getting enough nutrients from the soil. However, if we observe, we will see that the use of organic chemical fertilizers is very low in all the crops that have vegetables. Still, many times the farmers of our country use organic chemical fertilizers to increase soil fertility.
When growing crops in paddy land, the first thing to consider is whether there is adequate water supply and then there is a need for soil fertility and soil quality. In this case, I think that if the quality of the soil is maintained, then in that case the use of organic chemical fertilizers is less and in this case, in the presence of sufficient water, these crops will do well in the land. Many times it is seen that after cutting the paddy plant from the land, some paddy remains on the land and from there the paddy plant grows. It can even be seen that even without proper care, the paddy plant can produce crops. In this case, it is understood that organic chemical fertilizers are mainly used to improve soil quality and fertility. Since Bangladesh is a country after Kishore and since the soil in different parts of this country is fertile, I think that the use of organic chemical fertilizers for the cultivation of various vegetables including paddy, wheat and corn can be done even if less.
Bangladesh is a rice paddy country and the main crops produced in this country are rice, wheat, maize, jute etc. I have come to know the names of some pesticides related to the use of pesticides in rice from the text book, now I will list them before you.
Fungicide Oxycob 50 WP : Protects crops from diseases such as leaf blight of rice, brown spot, slimy brown spot, dry rot of vegetables, dieback of pepper, late blight of potato and tomato. (Application rate: 700 grams per acre)
Herbicides Islet 15 WG : This insecticide is effective against all weeds including rice sedge and broadleaf weeds and jute weevils. (Application rate: paddy 40 grams, jute 80 grams per acre)
Insecticide Ultima Plus 40 Wg : Controls rice borer, brown planthopper, leafroller and brinjal tip and fruit borer, bean and sorghum fruit borer, cotton aphid, jassid and ballworm and soybean tip and fruit borer. Suppresses fruit borers. (Application rate: 30 grams per acre.)
Insecticide Ashathion 57 EC : Protects crops by suppressing rice brown planthoppers, gandhi and leafhoppers, brinjal tip and fruit borers and bean jab beetles. (Application rate: 400 ml per acre)
Insecticide Ashabyan 48 EC : Protects crops by suppressing various insects including rice borer, leafhopper, leaf-roller, leafhopper and grain cutworm, and vegetable jab and potato borer. (Application rate: 200 ml per acre on rice and 600 ml per acre on potato)
Insecticide Emacarb 25 WG : Protects crops by successfully suppressing rice borer, brinjal tip and fruit borer, bean, sorghum fruit borer. (Application: Only 100 grams per acre)
Fungicide Emixor 32.5 SC : Beneficial to crops by suppressing all diseases including rice husk burn, blast, banana sigatoka, panama, pepper leaf spot, mango anthracnose and powdery mildew and all fungal diseases of vegetables. (Application rate: Paddy 200 ml, Banana 100 ml, Chilli 100 ml per acre)
Insecticide Weight 95 SP : Highly effective insecticide against all types of harmful insects including rice borers, vegetable fruit borers and suckers which suppresses harmful insects and benefits crops. (Application rate: 150 grams per acre)

Observations and suggestions:
At present, it is the most damaging to crops. At present, chemical methods are most widely used to control pests from cropland. Ferroman roofing is the most widely used biochemical method which you rightly mentioned. While the use of copperoxychloride in BLB can quickly suppress the plague, it also has some disadvantages. I was surprised to learn that Ultima is still used in your area for pest control. You wrote very well.
