Weed Biology Part 2 : Stages of Growth

Last week we covered the differences between monocots and dicots. (If you missed it, click here.) The next step to effective weed management is to be able to understand and identify the four different stages of growth. The effectiveness of pesticide applications will vary depending on the phase of the growth cycle. Since the purpose of this series is to talk about weed biology, I’ve focused on the life cycle of weeds which can differ from turf and ornamental plants. Most weeds are annuals which we’ll cover in more detail next week.

Phase 1: Seedling

As you might guess, the seedling phase is when all plants (weeds and desirable plants alike) are the most tender. Seedling are the infants of the plant world. Seedlings have immature root and shoot systems. The water and nutrient content of the soil needs to be almost perfect. Any disturbance in the root system will be highly detrimental if not fatal. A pesticide application can be severely detrimental to seedlings even if the pesticide is not an herbicide. Mechanical controls are also highly effective in managing seedlings. When using mechanical controls take care not to damage any seedlings of the desirable plants, for example turf.

Phase 2: Vegetative

During the vegetative stage weeds go through an enormous amount of growth. This is the pre-teen/teenagers of the plant world. Weeds in the vegetative stage are taking up as much water and nutrients as their roots can find. This is why dandelions appear to spring into existence almost overnight. The number of stems and roots increase rapidly during this phase making weeds a little harder to pull by hand. However, since the weed is actively growing, any systemic pesticide applied will be moved through the plant quite rapidly. Non-selective systemic herbicides will be highly effective during this phase of growth.

Phase 3: Flowering/Seed Production

By the time the weed reaches the flowering/seed production phase it will have reached “full size” and has started directing energy toward flower and seed production. Weeds in this phase are the young adults of the plant world. Water and nutrients taken up are directed toward flower and seed production instead of shoot and root growth. The effectiveness of herbicide applications will be slower if not overall less effective than at the seedling or vegetative phase in the plant’s life. Systemic non-selective herbicides will still kill the whole plant, but it may take a week and a half or more instead of a few days.

Phase 4: Maturity

The final phase of weed growth is maturity. They’ve germinated, grown, flowered, and set seed. They’re done. There is very little, if any, weed growth during this phase. Demand for water and nutrients is very small, and there is very little energy production. Annual weeds have reached the end of their lifecycle and will die, biennial and perennial weeds will enter a dormant period. Herbicides applied at this phase will be largely ineffective. With no demand for water or nutrients the herbicide will remain localized in the leaf.

Understanding the lifecycle of weeds and being able to identify each stage of lifecycle is an important skill for turf and ornamental managers. Pesticides are an effective tool in the never-ending battle with weeds like dandelions, but knowing when to apply pesticides will save time, money, product, and help keep pesticides out of the environment.

Invasive or Non-native? What’s the difference?

Invasive plant species have been a hot topic in recent months. Everything from wild mustard to milfoil. But it wasn’t until I was at a city commission meeting with my daughter a few months ago that I realized that non-native seems to have become synonymous with invasive: there was some construction work that needed to be done and the contractor was wanting to have 60 year old Chinese Elm trees removed citing them as invasive.

As I was watching these city commissioners nod their heads in agreement while discussing the removal of these big beautiful trees I realized than many if not all of the commissioners weren’t aware of the difference between invasive plants and non-native plants.

So what is the difference between invasive plant species and non-native plant species? According to the Michigan Invasive Species home page, “An invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan’s economy, environment, or human health.”

The key words here are “causes harm.”

In Michigan, an invasive species that is getting a lot of attention right now is garlic mustard (Alliaria petiolate). Garlic mustard thrives in wooded areas and can tolerate deep shade, partly because it emerges and blooms before trees develop leaves in the spring. It’s choking out the native plants causing harm to the ecosystem.

Another invasive that’s getting a lot of attention is giant hogweed (Heracleum mantegazzianum). The sap of the giant hogweed can cause a severe skin reaction that can cause the skin to blister when exposed to the sun. This invasive plant causes harm to humans.

Both of these plants are invasive.

However, let’s look at a well-known landscape plant – the hosta. Hostas are native to Asia. They have become a very popular plant for shaded plantings. They are non-native, but not invasive. Another example is purple coneflower (Echinacea purpurea) which is a popular plant for sunny locations and even has some medicinal properties. And while both of these examples are spreaders, they are not invaders as they cause no harm to surrounding ecosystems.

The short version is to remember that non-native does not equal invasive, select plants for the landscape that are best suited to each planting site, and consult your state’s invasive plant species list before planting.


Emergency Response to Pesticide Exposure

This is a snippet from Certified Training Institute's Personal Protective Equipment Course - Approved for Continuing Education in Multiple States

Unfortunately, accidents happen. Some are small and fairly manageable and others big or hazardous that require expert assistance. You need to be able to identify how unintended pesticide releases, like fires and spills, can harm humans and the environment. In dealing with emergencies, you must know how to clean up and dispose of contaminated items to reduce environmental impact. And, you should be familiar with emergency response equipment.

Be prepared. The more prepared you are to handle an emergency, the faster you can react to reduce impacts on human and animal health, and reduce impacts to the environment.

What is a typical emergency when working with pesticides?

  • If a vehicle or spray rig overturns, pesticide injuries, fires, or spills can occur.
  • A ruptured hose can cause a pesticide spill that results in an exposure incident or environmental contamination.
  • An explosion or fire in a pesticide storage area can result in toxic fumes.

Why is it important to plan for an emergency response? 

  • Being well-prepared to respond to an emergency can prevent harm to humans and the environment.
  • How you respond makes all the difference and will likely diminish the consequences that may develop.

Develop a Plan

Designate an emergency coordinator for your organization’s emergency response plan. The plan should include a list of agencies to be notified, including the person to contact. Have phone numbers for the local emergency planning committee, police and fire units, and the local paramedics and hospitals. List the chemical manufacturer’s contact information for the pesticides used. Include agencies that are responsible for pesticide containment and hazardous waste clean up. Don’t forget to protect yourself and your assets. Contact an attorney if there is an emergency involving pesticides and remember that ignorance of the law is no excuse.

Emergency Response Forms.  Report information about the incident on emergency response forms and keep them with the phone number list.

Provide Maps. A map of the pesticide storage facility and bulk storage tanks is essential to assist emergency responders and employees. Include the layout of the storage areas, access roads and fences, main shutoffs for utilities, and the location of fire alarms, extinguishers and personal protective equipment. Make sure emergency response agencies have a current copy available in the event an incident occurs.

Provide the emergency response agencies with an area map that directs them to the pesticide storage facility without delay. Even with the advent of 911 emergency and geospatial positioning systems, some remote areas may not have adequate communications/map access.

Hawaiian Farm Pays $550,000 For Failure to Comply with Worker Protection Standards (WPS)

A Hawaiian Farm is accused of using a pesticide known as Lorsban Advanced incorrectly and failing to notify workers to avoid the field. Furthermore, the farm allegedly allowed and directed workers to enter the treated fields before an adequate amount of time had passed, without protective gear or access to decontamination supplies.

The Hawaii Department of Agriculture began an initial investigation in January of 2016 and deferred the case to the EPA for enforcement later that year. The EPA determined that the farm was in clear violation of the FIFRA Worker Protection Standard Regulations. In February of 2018 the farm reached an agreement with the EPA to pay $400,000 on eleven WPS training sessions and a $150,000 civil penalty.

Not only will the farm be required to provide $400,000 worth of Worker Protection Standard Trainings, but they must also develop compliance kits in 4 languages to accommodate the diverse populations of Hawaii, Guam, and the Northern Mariana Islands where the company has commercial farms.

Worker Protection Standard enforcement has not been widely advertised, however, as seen above, repercussions are steep and costly. Training your staff before a problem occurs is a preventative measure that will help you avoid costly lawsuits, medical bills, fines, and save your business’s reputation.

The Hawaii Department of Agriculture found several pesticide safety violations at Wonder Farms, Inc during inspections conducted between 2012 and 2015. EPA inspectors discovered the company was out of compliance with the EPA's Worker Protection Standard and fined them $26,700.

Wonder Farm faced penalties for failing to:

  • Provide workers with information necessary for their safety regarding pesticide applications, including the location of the treated area, the product used, active ingredients, time of application, and any restrictions to entry.
  • Ensure that its workers and handlers had received pesticide safety training.
  • Post pesticide safety information in a central location after pesticides had been applied.
  • Ensure handlers used the required protective clothing, such as waterproof gloves and eyewear.

EPA inspectors also discovered that Wonder Farm applied pesticide products to their basil containing malathion, carbaryl, and dimethoate as active ingredients. These active ingredients are not authorized for use on basil. Wonder Farm also failed to follow the instructions found on the pesticide labels that set the approved application and frequency of use for crops, failed to properly clean leftover, non-refillable pesticide containers, and improperly used pesticides for cleaning spray tanks.
