Biopesticide-based Area-Wide Approach to Managing Codling Moth in Michigan Apple

Eight growers managing more than 800 contiguous acres of apple utilized pheromone-based mating disruption, codling moth granulosis virus, and recently registered conventional products, such as Calypso* (thiacloprid) to effectively control codling moth. Captures of male codling moth in pheromone-baited traps were significantly reduced from the first to the second generation. Fruit injury was 76% lower in area-wide orchards at harvest as compared to non-disrupted orchards outside the project area. Fruit injury at harvest was about 0.5% in plots relying on virus and Calypso* to supplement the disruption program, as compared to 2% in plots treated with pheromone and standard insecticides.

Effectiveness of Nematodes and Fungi Against Plum Curculio

The use of entomopathogenic nematodes and fungi in laboratory and field tests was researched to assess their efficacy against plum curculio. Contained within this goal was the attempt to procure materials approved for organic certified growers. Results showed that of the four nematode species studied, Steinernema riobrave significantly reduced adult plum curculio emergence versus controls. S. carpocapsae also reduced emergence but only in certain treatments. Further research is necessary to determine the efficacy reduction of S. riobrave over a longer time period.

Effects of Intentional Gaps in Spray Coverage on the Efficacy of Gypsy Moth Mating Disruption

A 2008 study was conducted in forested areas in Virginia to examine the effects of gaps in coverage of pheromone on gypsy moth mating disruption. The results suggest that it may be possible to lower costs associated with gypsy moth mating disruption applications by alternating treated and untreated swaths, which would reduce flight time and fuel costs, without a reduction in efficacy.

Potential of Mycotrol O* for Control of Blueberry Maggot Fly Adults

The four studies conducted in 2009 with Mycotrol O* suggest that soil drenches of Mycotrol O* are not effective against the blueberry fly. Foliar treatments may show some promise; although, the study comparing Mycotrol O* to a non-treated check and a combination of Mycotrol O* and GF-120* suggested that Mycotrol O* may not be effective in the field. The foliar exposure shows that flies do develop mycosis when exposed to blueberry foliage with inoculum; however, inoculum delays quickly so that by 72 hours after application, little mycosis occurs.

Rotation of Biopesticides and Traditional Chemicals for Management of Onion Thrips

Despite intensive insecticide use for management of onion thrips, control remains difficult. In this context, effective rotational adaptation of biopesticides with conventional pesticides for thrips management in onion would be a breakthrough in onion production. In 2009 rotation of several biopesticides with traditional chemicals was tested at Oregon State University. This is a second year research project funded by IR-4. The same rotations were followed both years. However, in 2009, additional treatments were also conducted in Canada. Several biological pesticides rotations significantly reduced thrip numbers. Only a preliminary analysis is presented on this report at this point in time.

Control of Septoria Blueberry Leaf Spot Diseases Through Use of Foliar-Applied Phosphite-Containing Biopesticides

As many as five conventional fungicide applications are typically required for adequate control of Septoria leaf spot, and even more sprays may be needed on cultivars susceptible to other leaf diseases that appear later in the fall, such as anthracnose and rust. Control has been largely limited to stobilurin products (Cabrio*, Abound*, or Pristine*), chlorothanonil or Aliette*. The efficacy of the biopesticides ProPhyt* and Agrifos* (potassium phosphite) was very similar to that of the conventional strobilurin fungicide, Cabrio*, the chemical standard for this trial. In addition, ProPhyt* alternated with the Cabrio* yielded disease suppression similar to that of Cabrio* alone, which would allow the biopesticide’s use in a resistance management program. As a result of this demonstration, producers have started using the phosphate biopesticides throughout the blueberry growing region of Georgia, and Extension has begun to recommend the phosphite biopesticides within IPM programs.

Demonstrating the Efficacy of Biofungicides Within a Management System for Powdery Mildew on Cantaloupe

A field trial was conducted in late spring 2009 at the University of Arizona to determine the effectiveness of two biopesticides in controlling disease in a cantaloupe planting. Actinovate* and Kaligreen* were applied alone or in rotation with one of three different conventional fungicides. Four applications of the biopesticides alone at weekly intervals reduced powdery mildew at crop maturity by 30% compared with non-treated plants. Data from this study demonstrate that incorporating biofungicides into a disease management program containing a highly efficacious conventional fungicide, such as Quintec* or Procure*, can provide effective control of powdery mildew on melons.

Demonstration of Effectiveness of Serenade* (Bacillus subtilis) for Control of Fire Blight in Apples and its Utilization Within an Apple IPM Program in the State of Washington

Fire blight is currently controlled by conventional growers through the use of antibiotics, including streptomycin and oxytetracycline. Agricultural use of these antibiotics raise concerns regarding the resistance development and subsequent impacts on medical uses of these same antibiotics. Serenade* (Bacillus subtilis) is a biopesticide alternative that is being investigated in this project. Serenade* ASO, while not performing at a level of the various antibiotics, appeared to control fire blight infection to a greater degree than in similar tests carried out by the principal investigator in 2003 and 2004. The use of Serenade* during the three or four day period prior to infection, during which bacterial levels are building to dangerous levels, appears to disrupt the development of large colonies of disease organisms (Erwinia amylovora). Thus, pre-infection use of Serenade* could reduce the numbers of antibiotic sprays, while at the same time maintaining their effectiveness.

Effectiveness of Serenade*, Sonata*, and Potassium Bicarbonate Within a Biopesticide Intensive IPM System for Management of Powdery Mildew on Cantaloupe

Disease ratings at plant maturity revealed that reduction of powdery mildew due to three applications of Serenade* (B. subtilis), Sonata* (B. pumilus) or Kaligreen* (potassium bicarbonate) alone was 32%, 29% and 24%, respectively, whereas similar application timing for the conventional fungicide Procure*, was 98%. In treatment programs where the conventional fungicide was rotated with one of the above pesticides, reduction of powdery mildew by Procure* alternated with Serenade*, Sonata*, or Kaligreen* was 95%, 98% and 95%, respectively. The degree of disease control achieved (mean of 27%) when biopesticides were alternated (Kaligreen* alternated with Serenade*, or Kaligreen* alternated with Sonata*) did not differ from that of each biopesticide applied alone (mean of 28%). The results of this trial suggest that effective control of powdery mildew could be achieved within an IPM system employing a rotation treatment program between the conventional fungicide Procure*, and the biopesticides Serenade*, Sonata* or Kaligreen*, affording a 33% decrease in the use of conventional fungicides.

Efficacy of a Germination Stimulant and Fungicides on Control of White Rot of Garlic and Onion

Currently, the only effective method of control of white rot in garlic and onion is tarped fumigation with methyl bromide. This method may kill most of the sclerotia in a treated field, but it does not result in complete eradication. Therefore, re-treatment has to be made on an on-going basis, since the presence of a few viable sclerotia remaining in a field can result in disastrous consequences for Allium production. The use of DADS* sclerotial germination stimulant reduced the population of sclerotia in the soil by up to 90%. However, as with methyl bromide, the remaining sclerotia are sufficient to cause high levels of white rot. Use of conventional fungicides effectively reduces the incidence of white rot, but does not cause sclerotial mortality in the soil beyond the treated area. Therefore, DADS* may be an important part of an IPM system to manage white rot, and is an effective substitute for methyl bromide to limit the spread of white rot to other fields, Repeated applications of DADS* over the course of two or more years may provide levels of mortality that might reduce the need for conventional fungicides.

Foliarly Applied Aliette* and Prophyt* on Avocado Trees is not Phytotoxic

Research has demonstrated that properly timed applications of foliarly applied phosphonates are effective in preventing avocado tree decline or death due to Phytophthora root rot. However, there are concerns that foliar applications of phosphonates in conjunction with regular foliar applications of copper fungicide would be phytotoxic to leaves and fruit. To answer these concerns, field and container demonstrations were initiated to assess the risk for phytoxicity following foliar applications of phosphonate (ProPhyt* or Aliette*) and copper. No phytotoxicity to leaves, stems, or fruit was observed. Economic analysis found ProPhyt* applications to be 55% less expensive than Aliette* applications.

A 2008 demonstration was conducted on the impact of AflaGuard* on the level of aflatoxin in irrigated and non-irrigated peanut. Aflatoxin is a toxin produced by the fungal pathogens Aspergillus flavus and Aspergillus parasiticus. The peanut industry has a threshold of 15 ppb for aflatoxin in peanuts used in commercial human consumption. Many European processors have a 0-4 ppb threshold. AflaGuard* is a non-toxigenic strain of A. flavus. Research determined that increasing the population of the non-toxigenic strain of in the soil dramatically reduced the percentage of harvested peanut loads exceeding the 15 ppb level of aflatoxin.

Interactions between Coniothyrium minitans and Sclerotinia minor affect Biocontrol Efficacy of C. minitans

In this experiment the interactions between C. minitans and different growth phases and MCGs of S. minor were evaluated. Analysis of variance using mixed model revealed that C. minitans significantly reduced (P <0.0001) sclerotial production at all three growth phases of S. minor tested in all four MCGs and the mycelial phase of S. minor is the most sensitive phase to C. minitans.

Managing Phytophthora capsici on Pepper with Combinations of Tenet* and Conventional Fungicides

This study evaluates the effectiveness of managing Phytophthora capsici on peppers with combinations of Tenet* and conventional fungicides. While most of the treatments significantly reduced disease compared to the untreated check, applications of Tenet* in conjunction with Presidio*, Ridomil Gold* and Copper showed a tendency to enhance disease suppression compared with application of these product alone.

Managing Sclerotinia Stem Rot of Canola through the use of Biological Control Agents

Native populations of biocontrol agents attack the sclerotia in the soil. Every sclerotium that comes under attack is food to produce millions of new spores of the biocontrol agents. Since these beneficial organisms do not move in the soil, distribution in fields may be scattered. Yearly broadcast application of C. minitans results in uniform distribution and better levels of control. Combination of yearly applications and crop rotations will result in better, longer control of Sclerotinia.

Reduced-Risk Management of Peach Rusty Spot

Two biopesticides, Bacillus subtilis (Serenade*) and potassium bicarbonate (Kaligreen* and Armicarb*) in rotation with the conventional fungicide Nova* yielded results equivalent to four applications of the conventional fungicide alone. These results demonstrated at a commercial level that the integration of reduced-risk biofungicides in rusty spot management programs can lower usage of conventional fungicides by 50% without any loss of control.

Regalia and Pristine Against Brown Rot and Shot Hole of Almond and Anthracnose and Botrytis of Strawberry

Regalia SC* was tested for its effectiveness against brown rot and shot hole disease of almond and anthracnose and Botrytis on strawberry. In Peerless almond, Regalia* in alternation with Pristine* was most effective, reducing the number of blighted shoots per tree to 50% of disease levels obtained on water-treated trees. Regalia* alternated with Pristine* also lowered shot hole symptoms on leaves. In Camarosa strawberries, the trial showed no statistically-significant differences among treatments. There was no significant difference on Botrytis. Data tentatively suggests that Regalia* in rotation with synthetic fungicides may lower reliance on synthetic materials while maintaining effective disease management.

Responses of Cucumber Seeds Slurry Coated with Trichoderma Species to Planting in Growth Media Infested with Pythium aphanidermatum

BW240 WP (Trichoderma harzianum T-22 and T. virens G-41), Subdue Maxx* (Mefanoxam), RootShield* WP (T. harzianum T-22 ) and RootMate* WP (T. virens G-41) were evaluated for suppressiveness to Pythium damping-off of cucumber caused by Pythium aphanidermatum. Though each seed treatment significantly suppressed damping-off, BW240 WP was the only treatment that was completely suppressive to the disease. In addition, suppression by the BW240 WP drench was consistently highest among all drench treatments.

Use of Phosphite Materials for Control of Pythium Species in High-Density Blueberry Production Systems

The phosphite biopesticides (ProPhyt* and Agrifos*) provided results equivalent to the conventional fungicide Ridomil*. In addition, biopesticide/Ridomil* rotations provided significant improvement in vigor and survival in the initial year of planting. With ProPhyt* and AgriFos*, costs are less than 1/3 that of Ridomil* with similar to equivalent efficacy. The phosphites have great potential value to the blueberry industry, both in terms of efficacy, and risk reduction.
