AI Technical Summary

Problems solved by technology

It is estimated that approximately 40-70% of the nitrogen, 80-90% of the phosphorus and 50-90% of the potassium content of applied fertilizers is lost in the environment and does not reach the plants, which results in ongoing and economical losses

Embodiment 1

[0125] Example 1: XPclad Efficacy

[0126] The minimum effective dose (MED), optimal dosing regimen (ODS) and safety profile of XPclad nanoparticles were determined. Measuring the antifungal activity (IC 80 ), and to quantify changes in soybean growth caused by fungicide-containing XPclad nanoparticles compared to using other fungicide application methods.

[0127] Minimum effective dose (MED), optimal dosing regimen (ODS) and safety measures

[0128]Evaluation of the MED assay and optimal schedule in SBR fungi following inoculum preparation and inoculation after establishment of the inoculum in MED plates with 0.1 μg, 0.2 μg, 0.4 μg, 0.8 μg, 1.6 μg and 3.2 μg per day Triazole (trade name Tilt250EC / Bumper 25EC)- and methoxyacrylate (trade name Bankit) treated fungi alone, or similar amounts of triazole and methoxyacrylate in XPclad nanoparticles (per cm area), no treatment, or treatment with XPclad nanoparticles (triazole and methoxyacrylate free). For the optimal dosing...

Embodiment 2

[0137] Example 2: XPclad targeting and environmental stress

[0138] In pot experiments, soybean seedlings were individually treated with coronatin-coated XPclad nanoparticles containing methoxyacrylate + triazole, uncoated XPclad nanoparticles, or methoxyacrylate alone + triazole. Plant growth parameters (stem weight, plant height, number of pods and seed weight / plant) were recorded within 3 months and after sowing with or without P. pachyrhizi challenge. Scanning electron microscopy and mass spectrometry (MS) were used to precisely quantify the (extracellular and intracellular) localization of XPclad nanoparticles in leaves and pods. Similarly, gas chromatography and mass spectrometry (GC-MS) was used to determine the residual fungicides present in potting soil.

[0139] Plant Material and Propagation

[0140] 5B066R2 and 5B024R2 soybean seeds (Mycogen Seed Company) were sown in 12 cm diameter pots (two plants per pot) in soilless mix (Sunshine Mix, LC1; Sun Gro Horticu...

Embodiment 3

[0165] Embodiment 3: nanometer fertilizer

[0166] Preparation of nanofertilizer formulations containing macronutrients (N, P, K) or micronutrients (Zn, Mo, B). The size and zeta potential distributions of the nanofertilizers are shown in Figures 5A-5D . The Log P values ​​of nanofertilizers are shown in Table 3.

[0167]

[0168] Further experiments will show that coated and uncoated nanofertilizer formulations have good delivery of macronutrients and micronutrients in a number of test settings. In some embodiments, the nanofertilizer comprises at least 15% (w / w) N-, P-, and K-containing compounds, and at least 8% (w / w) amino acids. In some embodiments, the nanofertilizer further comprises at least 10 per unit 12 beneficial bacteria.

Abstract

The present application relates to a nano particle compositions and methods for targeted delivery of a bioactive agent to a plant. In one embodiment, the nano particle composition includes a coronatine-coated nano particle formulated to deliver one or more bioactive agent through plant stomata. A variety of bioactive agents may be included in the nano particles, including one or more bactericides,fungicides, insecticides, acaricides, miticides, nemanticides, molluscicides, herbicides, plant nutrients, fertilizers, plant growth regulators, or combinations thereof.

Description

[0001] This application claims priority to US Provisional Patent Application Serial No. 62 / 314,836 filed March 29, 2016. The entire contents of the aforementioned applications are incorporated herein by reference. technical field [0002] The present application relates generally to nanoparticle compositions and methods for improving the bioavailability of macronutrients and micronutrients to plants and protecting against phytopathogens. Background technique [0003] Agriculture is a multi-billion dollar industry. Improved plant growth requires fertile soil. Fertilizers are often used on crops in the absence of fertile soil. Air and water supply three essential elements for plant growth, specifically Carbon (C), Hydrogen (H) and Oxygen (O). When chlorophyll (the green pigment) in plants is exposed to light during photosynthesis, these three elements combine to form carbohydrates and release oxygen. Water enters the plant by absorbing it from the soil through the rhizomes...
