Agriculture Pest and Weed Control

  There are a lot of reasons to control weeds. Weeds are unsightly, they can interfere with harvest, they can carry crop pathogens or host damaging insects, and most importantly they rob a crop of its yield potential. Weeds do compete with crops and reduce crop yield and crop quality, but how and when? The traditional answer is that weeds and crops compete for the same resources, light, water, and nutrients, but this is only part of the story. Plants have the ability to detect if another plant is growing nearby. They do this by detecting the light that gets reflected off nearby plants, which is of a different wavelength than light reflected off bare soil. Once weeds are detected, a crop may devote more resources into becoming more competitive, such as by growing taller, and less energy into producing seed. This change can happen early in the season, even before weeds and crop are competing for resources such as water or nutrients. So how soon do weeds need to be controlled? During ...

Preventative Weed Control Preventative weed control refers to any control method that aims to prevent weeds from being established in a cultivated crop, a pasture, or a greenhouse. Examples of preventative weed control would be using certified weed free seed, only transporting hay that is weed free, making sure farm equipment is cleaned before moving from one location to another, and screening irrigation water to prevent weed seeds from traveling along irrigation ditches. Cultural Cultural weed control refers to any technique that involves maintaining field conditions such that weeds are less likely to become established and/or increase in number. Examples of cultural weed control would be crop rotation, avoiding overgrazing of pastures or rangeland, using well-adapted competitive forage species, and maintaining good soil fertility. Mechanical Mechanical weed control refers to any technique that involves the use of farm equipment to control weeds. The two mechanical control techniques ...

 > They interfere in harvesting >They compete with crop plants for water, nutrients, space and light  >They affect plant growth >Presence of weeds increase the cost of agriculture and hinders the process of work >It increase the irrigation requirement >destroy native wildlife habitat and reduce natural food supplies >makes fire hotter and more destructive >hide feral animals and make them difficult to control

 Weed control is a type of pest control, which attempts to stop or reduces growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural setting preventing with native species. Weed control is important in agriculture. Methods include hand cultivators, smothering with mulch, lethal wilting with high heat, burning and chemical control with herbicides. (weed killers)

  ADVANTAGES  There are several advantages of pest control in public health and safety, these advantages underscores the important of pest control to both human health and the environment.  This includes: 1.Prevent Diseases > Most of the pest that keeps roaming about in our house carries diseases that can be easily transmittable to humans and animals. >Common house pests such as fleas, cockroaches and mosquitoes can transmit deadly diseases to humans including malaria, plague, dengue and surprisingly Asthma.  2. Promotes better sleep > Most of these deaths are because of malaria. >The better you sleep the more your health gets better, but one can not do that when having creepy pests around especially bed bugs. 3. Reduce allergies and itching >Common households pests including rodents, cockroaches and dust mites can all exacerbate allergy and asthma symptoms, especially in children. >Many pests bites causes severe allergies and itching all over the b...

 PREVEVENTING PESTS 1. Remove any source of food, water or shelter. 2. Store items in safe and enclosed containers. 3. Dispose of garbage regularly with a tightly closed lid. 4. Reduce clutter or areas where pests can hide. 5. Seal and close off any cracks or holes to eliminate outside entry. 6. Perform routine cleaning and surveying from the roof to the basement floor.   THE FOLLOWING LINK BELOW IS HOW TO CONTROL PEST IN CROPS                      https://goo.gl/cpbojR

  EFFECTS OF PESTS ON CROPS 1. Quality and quantity reduction . Pest reduces the produces quality and quantity as they eat up the produces on the farm even at storage. They reduce the nutritional quality of the produce as they release their saliva on the produce. Example is grasshopper, Grasshoppers are plant-eaters, with a few species at times becoming serious pests of cereals, vegetables and pasture, especially when they swarm in their millions as locusts and destroy crops over wide areas. 2. Disease vectors . Most insect pests are disease carriers. Example is Leafhoppers (family Cicadellidae) transmit over 80 known types of plant disease, including ones caused by viruses, mycoplasma-like organisms (MLOs), and spiroplasmas. Examples include aster yellows, beet curly top, blueberry stunt, dwarf disease of rice, phony peach, and Pierce’s disease of grapes. 3. Reduce rate of photosynthesis . Larvae of insect pest eat up the leaves and st...
