Definitions

• the present invention relates to the use of biological and/or chemical control agents for controlling nematodes or insects in nematode or insect resistant crops and to methods particularly useful for combating nematodes or insects and/or increasing crop yield in those crops.
• Nematodes are tiny, worm-like, multicellular animals adapted to living in water. The number of nematode species is estimated at half a million. An important part of the soil fauna, nematodes live in a maze of interconnected channels, called pores, that are formed by soil processes. They move in the films of water that cling to soil particles. Plant-parasitic nematodes, a majority of which are root feeders, are found in association with most plants. Some are endoparasitic, living and feeding within the tissue of the roots, tubers, buds, seeds, etc. Others are ectoparasitic, feeding externally through plant walls. A single endoparasitic nematode can kill a plant or reduce its productivity.
• Endoparasitic root feeders include such economically important pests as the root-knot nematodes ( Meloidogyne species), the reniform nematodes ( Rotylenchulus species), the cyst nematodes ( Heterodera species), and the root-lesion nematodes ( Pratylenchus species).
• Direct feeding by nematodes can drastically decrease a plant's uptake of nutrients and water.
• Nematodes have the greatest impact on crop productivity when they attack the roots of seedlings immediately after seed germination.
• Nematode feeding also creates open wounds that provide entry to a wide variety of plant-pathogenic fungi and bacteria. These microbial infections are often more economically damaging than the direct effects of nematode feeding.
• nematode resistance is characterized by host plant cell death at or nearby the feeding site of the parasitic nematode. Particular resistance genes and nematode interaction influence the timing and localization of the resistance response. Williamson et al. (Trends in Genetics, Vol. 22, No. 7, July 2006) describes the nature and mechanisms of plant-nematode interactions with respect to resistance in plants.
• Nematode-resistant plants can be related to three main approaches being nematode targets, nematode-crop interface and plant response.
• Antifeedant or nematicidal proteins, disruption of essential nematode gene expression by RNA interference, disruption of sensory function by RNA interference, peptides or plantibodies or nematicidal metabolites are examples for nematode targets; disruption of nematode pathogenicity factors regarding migration and invasion or regarding feeding site induction and maintenance by RNA interference, peptides or plantibodies, stealth or repellant plants; or the conversion of host plants to non-host plants are examples for nematode-crop interface while plant resistance gene or hypersensitive response activation by nematode invasion; Induced cell death or other site incompatibility by feeding site specific promoters or conversion of crops to tolerance are examples for plant response.
• nematode-resistant plants are described to be resistant towards specific nematodes, there is still some interactions between the nematode and the crop which, due to the different defense reactions of the plant, might lead to a partially impaired plant.
• One example of these defense reactions is the hypersensitive response.
• One consequence might result in impaired roots and loss of vigor of the affected plants.
• a large part of the damage to crop plants which is caused by pests occurs as early as when the seed is attacked during storage and after the seed is introduced into the soil, during and immediately after germination of the plants. This phase is particularly critical since the roots and shoots of the growing plant are particularly sensitive and even minor damage can lead to the death of the whole plant.
• it is desirable to develop methods for protecting the seed and the germinating plant which dispense with the additional application of crop protection agents after sowing or after the emergence of the plants. It is furthermore desirable to optimize the amount of active compound employed in such a way as to provide maximum protection for the seed and the germinating plant from attack by pests, but without damaging the plant itself by the active compound employed.
• methods for the treatment of seed should also take into consideration the intrinsic insecticidal properties of transgenic plants in order to achieve optimum protection of the seed and also the germinating plant with a minimum of crop protection agents being employed.
• the present invention is drawn to compositions and methods for regulating pest resistance or tolerance in plants or plant cells.
• resistance is intended that the pest (e.g., insect or nematode) is killed upon ingestion or other contact with the plant or parts thereof.
• tolerance is intended an impairment or reduction in the movement, feeding, reproduction, or other functions of the pest.
• Methods for measuring pesticidal activity are well known in the art. See, for example, Czapla and Lang (1990) J. Econ. Entomol. 83:2480-2485; Andrews et al. (1988) Biochem. J. 252:199-206; Marrone et al. (1985) J. of Economic Entomology 78:290-293; and U.S. Pat. No. 5,743,477, all of which are herein incorporated by reference in their entirety.
• controlling denotes a preventive or curative reduction of the insect or nematode infestation in comparison to the untreated crop, more preferably the infestation is essentially repelled, most preferably the infestation is totally suppressed.
• the present invention also relates to a method for the protection of seed and germinating plants from attack by pests, by selectively applying pesticidal agents to the seed of a transgenic plant.
• Pesticidal agents include chemical or biological control agents compositions applied to the seed of the transgenic plant, wherein the agent is intended to provide protection of the plant or seed thereof against damage caused by one or more plant pests.
• the invention relates to seed which has been treated with a pesticidal agent as described herein.
• a pesticidal agent to the seed of a transgenic plant results in an improved resistance or tolerance to one or more plant pests and/or improved yield or vigor compared to a transgenic plant cultivated from a seed not treated with a pesticidal agent as described herein, or a plant of the same species as the referenced transgenic plant that has been cultivated from a seed treated with a pesticidal agent as described herein but that lacks the transgene (either of which may be herein referred to as a “control” plant).
• treatment of the seed with these agents not only protects the seed itself, but also the resulting plants after emergence, from pests. In this manner, the immediate treatment of the crop at the time of sowing or shortly thereafter can be dispensed with.
• FIG. 1 shows the reduction in cyst counts for nontransgenic (Jack) plants compared to Axmi031 and Axn2 transgenic plants infested with soybean cyst nematodes.
• the seed of each plant was coated with a base seed coating only (no other chemical or biological treatment).
• the methods according to the present invention have been found to provide a greater degree of plant vigor and yield in nematode and fungal infested environments than would be expected from application of a biological or chemical control agent or the presence of an insect or nematode control gene alone. At least some of the insect control agents within the scope of the present invention have been shown to provide increased root mass even in the absence of insect pressure which increased root mass leads to improved establishment of the beneficial bacteria within the rhizosphere which, in turn, reduces overall losses in crop vigor and yields caused by either plant parasitic nematodes or fungi.
• compositions of the present invention have been formulated to provide a stable environment for living biological control agents such as spore-forming, root-colonizing bacteria.

• Protection against plant parasitic nematodes and fungi can occur through chitinolytic, proteolytic, collagenolytic, or other activities detrimental to these soilborne animals and/or detrimental to microbial populations. Additional protection can be direct such as the production of chemicals acutely toxic to plant pests or indirect such as the induction of a systemic plant response enabling a plant to defend itself from damage caused by plant pathogens.

• cfu colony forming units
• Jack an SCN resistant soybean variety with PI 88788 resistance
• AXN2 and AXMI031 Two genetically modified Jack varieties known to produce a nematicidal protein.
• the seed were treated with a color/coating base or the same base plus one of two different rates of fluopyram (experiment 1 used 0.075 mg fluopyram/seed and experiment 2 used 0.15 mg fluopyram/seed).
• the SCN used to inoculate both tests were collected from an inbred colony (OP50) with the ability to overcome PI 88788 resistance.
• Tests were conducted as non-randomized blocks with a minimum of 10 replicates. Seed were planted in individual 4′′ clay pots with coarse sand and inoculated with approximately 20,000 OP50 juveniles in ten equal inoculations beginning at planting and again approximately every third day. Plants were maintained in a germination chamber. Blocks were rotated approximately every third day to minimize potential influence of environmental variance. Two months after planting, plants were harvested and cysts were collected and counted to evaluate the efficacy of the nematicide and traits, both individually and in combination with each other.
• Fluopyram has not been shown to provide a positive growth response, which was also observed in the nontransgenic Jack plants in this experiment.
• fluopyram increased average plant height on both genetically modified varieties in both experiments while not having an effect on the nontransgenic control plants.
• fluopyram it appears as though the application of fluopyram to the transgenic Axn2 and Axmi031 plants overcame the growth inhibitory effects resulting from the presence of the transgene. There were no growth-promoting effects in the nontransgenic control, nor in the untreated transgenic plants.
• the percent control attributable to fluopyram would be expected to be less with the transgenic seed due to a potential overlap (e.g., fewer nematodes available for targeting by the fluopyram).
• the control achieved through the traits (20/43%—AXN2; 92/88%—AXMI31) did not diminish the effects of fluopyram.
• Fluopyram provided an approximate reduction of 20% at the low rate and an approximate reduction of 40% at the high rate for both Axmi031 and Axn2
• fluopyram resulted in a consistent level of nematode control despite the significantly lower nematode pressure resulting from the presence of the transgene.
• Glycine max (soybean) seed from an event traited with Axmi031 was selected.
• Axmi031 historically shows efficacy against species of nematode. Plants that screened negative for the presence of the transgene were used for control comparisons.
• Seed was treated with seed applied pesticides using a hege bowl treater.
• Metalaxyl (MTL) available as Allegiance through Bayer CropScience, was applied at rates of 2 and 4 g ai/100 kg seed.
• Trilex 2000 was also included as a commercial standard package.
• Plants with Axmi031 and metalaxyl had greater total mass and above ground mass than controls. Plant total mass increased by 13% in the presence of Axmi031 and an additional 5% at 2 g/a.i. of metalaxyl. The 4 g ai rate of metalaxyl resulted in a 11% increase in above ground plant mass compared to Axmi031 alone (Table 4).
• WinRHIZO analysis (Table 4) showed substantial root growth in plants with Axmi031 and metalaxyl compared to controls.
• Axmi031 as an individual component had values comparable to, or slightly below, the negative control.
• root lengths increased by 60% and 68%, root surface area by 42% and 37% and root volume by 27% and 11% for the 2 g ai and 4 g ai rates, respectively. Tips, forks, and crossings also increased as metalaxyl rate increased.
• Metalaxyl is not known to directly increase plant growth, but to protect seedlings from disease. It is unexpected for rates of metalaxyl to result in increased growth. Thus, the results of these experiments suggest that there is an interaction between Axmi031 and metalaxyl that results in plant growth promotion.
• Axmi205 historically shows efficacy against Diabrotica virgifera (western corn rootworm). The population of the seed used is not entirely transgenic; plants without the trait in their DNA were used for control comparisons.
• Seed was treated with seed applied pesticides using a hege bowl treater. Applications were made of: Clothianidin; available as Poncho though through Bayer CropScience. Rates were applied as mg ai/seed. The evaluation had non-target variables controlled.
• samples of each plant were submitted for PCR to determine if an individual plant carried the Axmi205 gene (positive or negative). Plants for which no PCR results could be obtained were not included in the results.
• Seed were planted into germination mix at a rate of one seed per root-trainer. Testing was conducted as a randomized complete block with 30 replications. Plants were maintained in a greenhouse and periodically assessed for emergence. After several weeks of growth, leaf samples were taken from plants and used to conduct insect bioassays on species of Lepidoptera. A leaf sample was placed into a Petri-dish and infested with 10 larvae of fall armyworm; Spodoptera frugiperda . After 48 hours dishes were evaluated for insect mortality and leaf feeding damage. When assessing leaf feeding, damage was recorded as a rating between 0-3, where zero was undamaged and three was severely damaged. After approximately three weeks from planting, plants were infested with Diabrotica virgifera (western corn rootworm).
• Diabrotica virgifera western corn rootworm
• Axmi205 is known to have efficacy on western corn rootworm ( D. virgifera ). There has been no evidence to suggest that Axmi205 is effective against any lepidopteran pests. Clothianidin when applied at commercial rates between 0.5 and 1.25 mg ai/seed can provide control of various corn insect pests. The rates examined in these trials were below recommended rates for labeled species.
• Mortality for S. frugiperda increased by 14%, 71%, and 57% above the negative control based on increasing rate of clothianidin. Mortality was increased further in the presence of Axmi205. Mortality increased by an additional 88% and 54% at rates of clothianidin at 0.125 and 0.5 mg ai/seed, respectively. Leaf feeding damage was also reduced by the combination of Axmi205 and clothianidin and appeared to correlate with increases in mortality (Table 5).
• Clothianidin is known to be efficacious on western corn rootworm when applied at recommended rates. The rates evaluated in this study are below label recommendations. Axmi205 reduced root damage by 37% over the negative control. The lowest rate of clothianidin tested reduced root damage by 67% over the negative control and the highest rate by 96%. At theses rates the high efficacy of clothianidin overshadowed any individual contribution of Amxi205. However, at a clothianidin rate of 0.25 mg ai/seed further root damage reduction of 69% was witnessed in the presence of the Axmi205 gene.
• Soybeans (6-10 seeds each) in this study included: Control SB171 (transfected control with non gene of interest); SB 171 treated with Bacillus firmus CNCM I-1582 spore control plant; Axmi031 transgenic plant (which also contains non gene of interest); Axmi031 transgenic plant (which also contains non gene of interest) treated with Bacillus firmus CNCM I-1582 spore.
• Soybeans (6-10 seeds/plant and treatment) were planted into 4′′ clay pots in sand infested with approximately 37,000 SCN eggs (HG2.5.7) at time of planting. Soybean plants were reinfested with 20,000 SCN eggs (HG2.5.7) at approximately 4 weeks post planting. Plants were grown 57 days post reinfestation date. Cysts were harvested from each pot and counted. PCR and Western analysis were done on each AXMI031 plant. Negative segregants were removed from analysis. Data shown in FIG. 2 represents six plants for SB171 each treatment and all PCR/Western positive Axmi031 plants.
