The main season for planting traditional maize is from Baishakh to Jeth. Crop experts say that maize will be a good crop in any region this season. Maize farmers have been worried since the fall Army Worms entered Nepal last year. For the management of fall army worm, the agricultural technicians had helped the farmers in their crops.But now the country is on the verge of collapse due to the global spread of coronavirus. Lakdown has not been able to reach the agricultural technicians in the villages. Ghanshyam Bhandari, a kit specialist at the National Maize Research Program, Rampur, has suggested various measures on how farmers can identify it themselves.
According to him, farmers can manage and identify army insects on their own with a little effort.
"Farmers buy pheromone traps from the market to find out if there are any army insects in the crop and hang them on the crop," he said. "If there are mother insects, they will hang on the pheromone traps and die." It gives an idea of whether or not military insects have infested Bali. ' According to him, military insects can also be checked on the basis of damage. If it is infested, the corn leaves look white. Similarly, the direction of insects can be seen in the corn husk.
If you look at the corn kernels, you will find insects there. If there are 4 holes in the back of the insect, it is a military insect.
How to manage?
If there are small insects, you should add neem based pesticide. If there are larger species of insects, he suggests using safe pesticides. According to him, the Ministry of Agriculture and Livestock Development has recommended six types of pesticides after conducting various studies and research. Emamectin benzoate 5% S. in cases of perforation of corn leaves and signs of damage to the gut. He recommends spraying G.0.4 gm per liter of water.
Similarly, neem-based pesticide Azadirachtin should be sprayed by mixing 1500 ppm percent per liter of water. In the case of organic pesticides, bacteria-based pesticides like Mahashakti, Dipel should be sprayed in 2 ml or 2 grams per liter of water, he said.
According to him, chlorantraniliprole contains 18.5 percent S.G. Spray with 0.4 ml per liter of water, Spinosad 45% SC 0.3 ml per liter of water and Vaspinatoram 11.7% SC.0.4 ml per liter of water. Imidachlorprid 48% FS should be sprayed in 4 ml per kg of seed.
He said that the same pesticide should not be used continuously and should not be used after the cocoon has been applied. When spraying pesticides, he suggests to use 25 liters of pesticide prepared solution of maize planted in one plantation and spray the prepared solution on the seedlings. ‘According to our traditional farming, farmers spray pesticides all at once through pipes. Insects do not die in such a way, 'he said, adding that since these insects chew and eat, medicine should be put in every gubo-gubo.'>
He says that farmers have to work harder for this. He has experienced that the use of pesticides in this way reduces the number of army insects. Apart from this, the scientists of the Department of Entomology of Narc have also given other suggestions for the management of military insects.
Insect infestation can be minimized by deep digging before planting maize, planting of snail-covered sorghum maize, timely sowing of kharif maize without delay as much as possible and planting at the same time in a certain place at the same time i.e. within a week.
Also, use the recommended fertilizer to make the plant healthy and strong and tolerate insect outbreaks. Since desmodium grass does not like this insect, it should be chased away by planting this grass in the middle of maize and using pesticides to attract this insect by planting its favorite Napier grass.
Farmers say that even if fine soil or ash is placed in the gubo, it is controlled. Cooking green khursani in cow's urine and mixing it with water in the ratio of 1:10 is also effective. Based on the maize planted in the National Maize Crop Research Program, this pest has caused a lot of damage from April to November and has less affected the demand for pus.
According to the ministry's report, the yield loss from this pest in African countries is 5 to 53 percent of maize production. He said that this insect, which mainly likes maize, harms junelo, paddy, wheat, millet, sugarcane, grass crop, banda, beetroot, almond, soybean, onion, cotton, turnip and potato.
