Combating fall armyworm and weed control

Crop protection is important to success in crop Production and general Agribusiness. The negative effects from pest and weeds have posed so much loss to farmers in my locality. My regular interaction with farmers on solution network programs has exposed me to most of the natural reason for low output and poverty in the rural areas. Recently, the major problems seeking attention and solution are

  1. Army worm invasion on maize crops
  2. Weeds and effective control measures

My idea for sustainable crop protection

I am preferably called farmers friend, I go down to the end of rural areas to interact and interrogate farmers on their needs. When I discovered the problems stated above and understood farmers failure due to lack of solutions I swung into action. Due to lack of finances, the fall army worm destroys maize farms to a loss in 2016 to 2017 farming year. Meanwhile the issue of weeds in the farms exists for decades now. Farmers in the rural communities lack the orientation to handle the situation due to lack of innovations and lack of access to improved agrochemicals. I was able to test and confirm some innovations on the two situations mentioned, the fall army warms and the weeds control. The innovations are;

  1. Use of Neem (Azadirachta indica) leaf juice with a combination of DIMETHOATE 40ec at a 200:1 liter ratio for single application for the maize life cycle. This has been tested at a demonstration plot in Muu, Gboko road Makurdi Local Government Area Benue State Nigeria. A farmland owned by Donald Akule of the prime multipurpose cooperative society Makurdi. The result was highly successful and mind blowing.
  2. Invention of a unique planting pattern that will give room for post emergent herbicides application on a mixed cropped farm. Due to the negative feedback gotten from farmers over the years on the refusal to adopt a single crop farming pattern for effective management and maximum output in my locality. The idea of precision came to play. My innovation idea allows a farmer to cultivate two crops with primary crop on 5 rolls before 50cm spacing to plant the secondary crop on another 5 rolls consecutively on the same piece of land. This allows ease of post emergent herbicides application without negative effect on either crops. Illustration: Primary crop vs Secondary crop

The innovations presented above have been demonstrated and the innovation is being transferred by Agribusiness Motivate Initiative in collaboration with a new agrochemical company from China called Hangzhou Agrochemicals Nigeria Limited. We transferred the second innovation to soybeans farmers in over 10 farm communities in 2018. The farmers reached are over 231 rural dwellers that practice mix cropping for soybeans and maize. Both crops with effective post emergent herbicides for good weed control.

 Last year, the precision farming innovation gave farmers who adopted it a triple yield record on a mixed crops farming pattern. In the previous years before the innovations, records on yield were 10bags of 100kg for maize which is usually the primary crop and 3 bags of soybeans which is the secondary crop per hectare. Meanwhile upon adoption of the innovation over 27 farmers out of 46 farmers who demonstrated the innovation recorded an average of 22 bags of 100kg/ha for the primary crop and 8bags of 100kg/ha for the secondary crop respectively (using the maize and soybeans farmers 2018 demo farms). It is obvious that such farmers will embrace the innovation in 2019 wet season without persuasion. This is because the innovation enhances high yield, effective weed control and management, low cost of labour which translates to high farm income. Farmers, agrochemical companies and government extension agents are the main stakeholders. If the innovation can be promoted by the government via these stakeholders, crop protection will experience an unimaginable growth rate across the nation.

As an Agribusiness expert and a Youth Coach in Agribusiness, my driving force is the passion to reduce poverty and enhance youth’s engagement is agriculture. Innovations that are flexible, teachable and further create opportunities for rural labour employment is my priority. Therefore, based on the easy, accessible, cheap and effective nature of the two innovations, farmers will surely adopt as seen in demonstrations done, farmers Economics of Production will be minimized by 17% from field experience and profit will be recorded. Consequently, my strife to promote business in Agriculture will be made easy, farmers financial status will improve, purchase of improve farm inputs will increase and there will be a clear economic development in the community for a better livelihood.

  1. Adopting practices that will increase farmer’s yield and moving away from traditional means of production should be emphasized. Keep on the good work!


  2. Very creative, Amy worm has been a nightmare for farmer. Recording losses on the farm.
    This innovative can be a game changer…


  3. Wonderful innovation, the article is detailed. I would love to meet the writer in person some day….he is a gift to Africa


  4. Very innovative and at least it would bring smiles to the faces of farmers. Armyworms has been a battle farmers always pray to win. Nice effort.


  5. Wonderful and splendid innovation, this is surely a game changer for we agriculturist, keep doing the good work and making us proud…


  6. This is a very good innovation and it will go a very long way in combating armyworm and the weed control which is one of the major problem in farm activation. So I really commend the work of this writer for putting smiles in the face of farmers 👍


  7. I suffered loss of my maize crops in 2017 due to army worm infestation. This article helps a great deal as I prepare towards another farming season.


    1. Great Invitation Man! Armyworm are nightmare to our farmers, so as weed control. This article is simple, well detailed & informative. It will go a long way in improving and increasing productivity (Crop Yield) and Lower the cost of production. More awareness is needed for Farmers to benefit from this great work. If i dont disseminate and Educate the farmers around me; Who will?Keep up the good work Bro


  8. Great idea you forward here Mr. Okolo.
    I wish this can be tried on a wider range of agro environments also so as to ascertain it’s relevance to other climes outside the area of study.
