MAXIM® Quattro – the new standard in traction against seedling diseases

Equipped with four active ingredients, MAXIM® Quattro deals with seed- and soil-borne diseases under a wide variety of conditions as effectively as your 4×4 deals with rough terrain.

Different species of Fusarium spp., Pythium spp., as well as Rhizoctonia solani, rob nutrients from the seed – which weakens the young seedling – and use it for their own survival. This leads to slow emergence and damping-off of the seedling, and reduces plant stand, vigour and ultimately yield.

Seed- and soil-borne diseases thrive under wide variety of environmental conditions. For example, Pythium will flourish in cool and wet conditions, while Fusarium does well when it is warmer and drier. Rhizoctonia is likely to infect in cool and wet conditions, while symptoms will show in warm and dry conditions.

This multi-pronged onslaught makes it extremely difficult to predict the prevalence and severity of each pathogen. Hence the best course of action is to implement comprehensive protection against seed- and soil-borne diseases from the get-go.

Figure 1: The diagram shows the wide variety of environmental conditions under which certain pathogens can thrive.

MAXIM® Quattro sets a new standard for comprehensive protection with four active ingredients that join forces to combat seed and seedling diseases.

MAXIM® Quattro’s four active ingredients each has a different mode of action; in combination they provide powerful protection against a broad range of diseases (Figure 2). Figure 2 also illustrates a unique feature of MAXIM® Quattro, namely that at least two active ingredients are in motion against a specific pathogen at any given time, which limits pathogens’ ability to build resistance.

Such comprehensive protection against seed- and soil-borne diseases, makes young seedlings resilient to diseases in a wide range of weather conditions. It also gives producers greater flexibility over timing of planting.

Twenty-seven demonstration trials were conducted to test the performance of MAXIM® Quattro under typical farming conditions. A positive response rate of 78% was achieved, with an average yield increase of 5.6% across all trials (Figure 3).

MAXIM® Quattro helps to reduce mycotoxin levels

Several Fusarium species can produce dangerous mycotoxins in maize, which are harmful to humans and animals. As a result, the scientific community and legislators are paying closer attention to mycotoxin contamination of food and feed.

In South Africa, 33 mycotoxin-producing Fusarium species have been associated with grain crops (Beukes, Rose, Shephard, Flett and Viljoen, 2017). Janse van Rensburg (2012) also stated that infection by fumonisin-producing Fusarium spp. (a group of mycotoxins derived from Fusarium and their Liseola section) is common in South African commercial maize samples.

MAXIM® Quattro protects seeds and seedlings against infection from Fusarium species, which helps to reduce mycotoxin levels in crops. Figure 4 illustrates the ability of MAXIM® Quattro to inhibit the growth of Fusarium verticillioides and Fusarium graminearum, which are two common mycotoxin-producing pathogens in South Africa.

Figure 5 shows the impact of MAXIM® Quattro on yield by comparing the number of healthy plants artificially inoculated with mycotoxin-producing Fusarium to non-inoculated plants and plants that had been treated with MAXIM® Quattro. Loss of yield is proportional to the number of kernels contaminated with mycotoxins. In plants inoculated with Fusarium graminearum and Fusarium from the Liseola section, the MAXIM® Quattro treatment obtained a significantly higher number of healthy plants, and therefore increased yields, compared to the inoculated check.

It is, however, important to note that the best results are achieved when MAXIM® Quattro is part of an integrated control program combining susceptible varieties and foliar programs.

4 reasons why MAXIM® Quattro sets the new standard for seed-applied fungicides

  1. It offers a combination of four active ingredients that are in motion against the most common seed and seedling diseases for comprehensive protection.
  2. MAXIM® Quattro encourages early plant development across a wide range of weather conditions, which gives growers greater planting flexibility.
  3. It protects seeds from Fusarium spp., which helps to reduce mycotoxin levels in maize crops.
  4. MAXIM® Quattro seed treatment translates into higher yields due to healthier crops.
