From your reality to the right solution.

The damage

Chewing pests that eat leaves, pods, ears and bolls. They reduce the leaf area that produces energy for the plant and directly attack what will be harvested. Under heavy infestation, defoliation drives yield down.

How to monitor

Weekly beat cloth sampling: count caterpillars per meter and assess the percentage of defoliation.

Biological strategy

A multi-front attack: Bacillus thuringiensis acts by ingestion and paralyzes the caterpillar's digestive system, Saccharopolyspora spinosa acts on the nervous system and Metarhizium anisopliae infects the pest on contact. It is effective control even on populations that no longer respond well to chemicals.

The damage

A sucking insect that pierces pods and grains. It leaves shriveled, stained and lighter grains, causes green stem syndrome and drives down yield and grain quality at the most expensive point of the season.

How to monitor

Weekly beat cloth sampling from the start of podding, during the coolest hours of the day.

Biological strategy

Chromobacterium violaceum acts on sucking pests by contact and ingestion, while Metarhizium anisopliae germinates on the stink bug, penetrates it and colonizes it. Two fronts of biological control that reduce the population without leaving chemical residue on the grain.

The damage

It attacks young plants right after emergence, especially corn following soybeans. Feeding on the stem leaves perforated and rolled leaves, tillered or dead plants and stand gaps that compromise yield from the start.

How to monitor

Inspection of the straw and the base of the plants in the early morning, counting stink bugs per square meter.

Biological strategy

Chromobacterium violaceum acts on stink bugs by contact and ingestion, and Metarhizium anisopliae infects the insect on contact, including those sheltering in the straw. Biological protection when the crop is most vulnerable.

The damage

A sucking pest that transmits the mollicutes and viruses of the corn stunt complex. Plants become stunted and reddish, with small, poorly filled ears, and the loss shows up when it is already too late to react.

How to monitor

Inspection of the whorl of young plants and yellow sticky traps in the field and along the edges.

Biological strategy

Beauveria bassiana and Metarhizium anisopliae are entomopathogenic fungi: the spores germinate on the insect, penetrate it and colonize it. The nymph and adult population drops and, with it, transmission of corn stunt.

The damage

It sucks sap, excretes sugary substances that favor sooty mold (a black fungus on the leaves) and transmits viruses, such as bean golden mosaic. The plant loses vigor and yield.

How to monitor

Weekly inspection of the undersides of upper-canopy leaves.

Biological strategy

Beauveria bassiana is a natural enemy of more than 700 insect species. It colonizes whitefly nymphs and adults and keeps the population under continuous control, while preserving the field's natural enemies.

The damage

They rasp and suck leaf cells, causing bronzing, premature leaf drop and poorer grain fill. They explode during hot, dry periods.

How to monitor

Pocket lens on the undersides of the leaves, especially at field edges and during dry spells.

Biological strategy

Chromobacterium violaceum acts on mites by contact and ingestion, and Beauveria bassiana colonizes the individuals that escape, breaking the reinfestation cycle.

The damage

Small rasping-sucking insects that attack shoots, flowers and young leaves. They leave silvery lesions and deformities and cause flower abortion.

How to monitor

Tap plant tips and flowers over a white surface and count the insects.

Biological strategy

Chromobacterium violaceum combined with Metarhizium anisopliae reaches thrips on young leaves and flowers, acting by contact and ingestion.

The damage

Aphid colonies suck sap from new shoots, curl the leaves and transmit viruses, reducing the plant's vigor and yield potential.

How to monitor

Inspection of new shoots and the undersides of young leaves.

Biological strategy

Chromobacterium violaceum and Metarhizium anisopliae act on the colonies by contact and ingestion, quickly reducing the population on the new shoots.

The damage

Microscopic worms that parasitize roots: they form galls and lesions and create patches of stunted, yellowing plants. The roots stop absorbing water and nutrients, and yield drops season after season.

How to monitor

Nematode analysis of soil and roots and mapping of the patches to track how they evolve.

Biological strategy

Pochonia chlamydosporia and Paecilomyces lilacinus parasitize nematode eggs and females, and Trichoderma harzianum protects the rhizosphere. Blend Bac reinforces this with Bacillus that form a biological barrier on the roots and stimulate rooting.

The damage

Soil fungi cause seedling damping-off, root and crown rot and wilt. White mold also rots stems and pods and leaves sclerotia that survive in the soil for years.

How to monitor

Counting damped-off plants, assessing roots and crown and recording areas with sclerotia.

Biological strategy

Trichoderma harzianum and T. viride colonize the soil and roots, compete for space and nutrients, parasitize pathogens and degrade sclerotia, and the inoculum in the area decreases every season.

The damage

Spots and lesions on the leaves reduce the photosynthetic area, bring defoliation forward and compromise grain fill.

How to monitor

Weekly inspection of lower-canopy leaves, where the spots start.

Biological strategy

Bacillus amyloliquefaciens, B. subtilis and B. pumilus produce antifungal compounds, compete with pathogens on the leaf surface and help the plant defend itself. It acts on Cercospora, target spot, brown spot and Fusarium and protects the efficacy of chemical fungicides in resistance management.

The damage

Much of the phosphorus applied gets bound to soil clays and never reaches the plant. The result: slow development, poor roots and expensive fertilization that does not return the investment.

How to monitor

Soil and leaf analysis and assessment of root development in the initial stand.

Biological strategy

Bacillus subtilis and B. megaterium solubilize phosphorus and other nutrients bound in the soil and deliver to the plant what has already been invested in fertilization.

The damage

Yellowing plants with few active (pink) nodules on the roots grow less and depend on mineral nitrogen: higher cost and lower yield.

How to monitor

Dig up a few plants about 30 days after emergence and count the pink nodules on the roots.

Biological strategy

Nitrogen-fixing bacteria form nodules on the roots that capture nitrogen from the air and deliver it to the plant, as well as stimulating phytohormones that expand the root system. It is nitrogen produced within the field, at a much lower cost per hectare.

The damage

Short, low-volume roots explore less of the soil. The crop becomes sensitive to dry spells and makes poor use of the nutrients applied.

How to monitor

Assess root volume and depth and stand uniformity in the first weeks.

Biological strategy

Azospirillum, Pseudomonas fluorescens and Bacillus aryabhattai produce phytohormones that stimulate root growth, increase root volume and ensure stronger, more uniform early growth.

The damage

Lack of rain and excessive heat halt growth and cause flower and pod abortion, losses that add up quickly.

How to monitor

Follow the weather forecast and watch for signs of plant wilting in the hottest hours.

Biological strategy

The Bacillus aryabhattai in Blend Zea improves the plant's adaptation to water stress, and the larger root system reaches water in deeper soil layers.
